As any of you who’ve already seen my precursor “2025 Look Forward” piece might bear in mind, we’ve deliberately flipped the ordering of my two end-of-year writeups as soon as once more this yr. This time, I’ll be trying again over 2024: for historic perspective, listed here are my prior retrospectives for 2019, 2021, 2022 and 2023 (we skipped 2020).

As I’ve completed in previous years, I assumed I’d begin by scoring the matters I wrote a few yr in the past in forecasting the yr to return:

• More and more unpredictable geopolitical tensions
• The 2024 United States election
• Home windows (and Linux) on Arm
• Declining smartphone demand, and
• Inside and exterior interface evolutions

Perhaps I’m simply biased however I feel I nailed ‘em all, albeit with various levels of impactfulness. To make clear, by the best way, it’s not that if the second would occur was tough to foretell; the end result, which I mentioned a month again, is what was unclear on the time. Within the sections that observe, I’m going to elaborate on one of many above themes, in addition to talk about different matters that didn’t make my year-ago forecast however ended up being significantly notable (IMHO, after all).

Battery transformations

I’ve admittedly written rather a lot about lithium-based batteries and the gadgets they gas over the previous yr, as I think I’ll even be doing within the yr(s) to return. Why? My introductory sentence to a latest teardown of a “vape” gadget solutions that query, I feel:

The ever-increasing prevalence of lithium-based batteries in numerous shapes, sizes and capacities is making a so-called “virtuous circle”, resulting in decrease unit prices and better unit volumes which encourage growing utilization (each in model new functions and current ones, the latter as a substitute for precursor battery applied sciences), translating into even decrease unit prices and better unit volumes that…spherical and spherical it goes.

Name me simple-minded (as a few of you already might have completed a time or few through the years!) however I persistently seek the advice of the identical checklist of traits and tradeoffs amongst them when evaluating numerous battery applied sciences…a listing that was admittedly round half its eventual size after I first scribbled it on a chunk of scrap paper just a few days in the past, till I saved considering of extra issues so as to add within the technique of keyboard-transcribing it (thereby ultimately encouraging me to delete the “concise” adjective I’d initially used to explain it)!

• Quantity manufacturing availability, translating to value (as I allude to within the earlier quote)
• Kind issue implementation flexibility (or not)
• The required dimensions and weight for a given quantity of charge-storage capability
• Each peak and sustained energy output
• The environmental impacts of uncooked supplies procurement, battery manufacturing, and eventual disposal (or, ideally, recycling)
• Talking of “environmental”, the usable working temperature vary, together with tolerance to different surroundings variables similar to humidity, shock and vibration
• And recharge velocity (each to “100% full” and to application-meaningful percentages of that complete), together with the variety of recharge cycles the battery can endure till it not can maintain sufficient anode electrons to be application-usable in a sensible sense.

Though loads of lithium battery-based laptops, smartphones and the like are offered right this moment, a notable “driver” of incremental utilization development within the first half of this decade (and past) has been numerous mobility methods—battery-powered drones (and, seemingly sooner or later, eVTOLs), cars and different autos, untethered robots, and watercraft (a number of examples of which I’ll additional elaborate on later on this writeup, for a unique motive). Right here, the design challenges are fairly interconnected and in any other case advanced, as I mentioned again in October 2021:

Li-ion battery expertise is fairly mature at this level, as is electrical motor expertise, so within the absence of a elementary high-volume expertise breakthrough sooner or later, to get longer flight time, you must embrace larger batteries…which ends up in what I discover most essentially fascinating about drones and their flying kin: the basic balancing act of buying and selling off numerous contending design elements that’s distinctive to the craft of engineering (versus, for instance, pure R&D or science). Have a look at what I’ve simply stated. Everybody desires to have the ability to fly their drone so long as doable, earlier than needing to land and swap out battery packs. However so as to take action, that signifies that the drone producer wants to incorporate bigger battery cells, and extra of them.

Added bulk admittedly has the aspect profit of constructing the drone extra tolerant of wind gusts, for instance, however essentially, the heavier the drone the beefier the motors should be with a view to raise it off the bottom and fly it for significant altitudes, distances, and durations. Beefier motors burn extra juice, which begs for extra batteries, which make the drone even heavier…see the quagmire? And in contrast to with earth-tethered electricity-powered gadgets, you possibly can’t simply “pull over to the aspect of the highway” if the batteries die on you.

Now toss within the added “twist” that everybody additionally desires their drone to be as clever as doable so it doesn’t find yourself misplaced or tangled in branches, and so it will probably mechanically observe no matter’s being videoed. All these picture and different sensors, together with the intelligence (and reminiscence, and..) to course of the information coming off them, burns juice, too. And don’t neglect concerning the wi-fi connectivity between the drone and the person—minimally used for distant management and analytics suggestions to the person…How do you steadiness all of these contending elements to provide you with an optimum implementation in your goal market?

Though the earlier excerpt was particularly about drones, most of the factors I raised are additionally related not less than to a level within the different mobility functions I discussed. That stated, an electrical automotive’s powerplant dimension and weight constraints aren’t fairly as acute as an airborne system’s is perhaps, for instance. This application-defined traits variability, each in an absolute sense and relative to others on my earlier checklist, helps clarify why, as Wikipedia factors out, “there are not less than 12 completely different chemistries of Li-ion batteries” (with extra to return). To wit, builders are testing out a variety of each anode and cathode supplies (and combos of them), more and more aided by AI (which I’ll additionally speak extra about later on this piece) within the course of, together with striving emigrate away from “moist” electrolytes, which amongst different issues are flammable and liable to leakage, towards safer solid-state approaches.

One other rising quantity development utility, as I highlighted all year long, are battery mills, most continuously showcased by me of their compact moveable variants. Right here, whereas kind issue and weight stay vital, for the reason that gadgets should be hauled round by their house owners, they’re stationary whereas in use. Extrapolate additional and you find yourself with even bigger dwelling battery-backup banks that by no means get moved as soon as put in. And extrapolate even additional, to a big diploma actually, and also you’re now speaking about backup energy models for hospitals, for instance, and even electrical grid storage for whole communities or areas. One compelling use case is to easy out the inherent availability variability of renewable vitality sources similar to photo voltaic and wind, amongst different causes to “feed” the seemingly insatiable appetites of AI workload-processing information facilities in a “inexperienced”-as-possible method.  And in all these stationary-backup situations, set up area is relatively plentiful and weight can also be of lesser concern; the first choice standards are elements similar to value, invulnerability, and longevity.

As such, non-lithium-based applied sciences will seemingly turn into more and more distinguished within the years to return. Sodium-ion batteries (courtesy of, partly, sodium’s familial proximity to lithium within the Periodic Desk of Components) are significantly near-term promising; you possibly can already purchase them on Amazon! The primary US-based sodium-ion “gigafactory” was just lately introduced, as was the US Division of Vitality’s deliberate $3 billion in funding for brand spanking new sodium-ion (and different) battery R&D initiatives. Iron-based batteries such because the mysteriously named (however not so mysterious when you learn the way they work) iron-air expertise tout uncooked supplies abundance (how typically do you come throughout rust, in spite of everything?) translating into low value. Vanadium-based “movement” batteries additionally maintain notable promise. And there’s one different grid-scale vitality storage candidate with an attention-grabbing twist: outdated EV batteries. They could not be sufficiently strong to reliably energy a transferring car, however stationary backup methods nonetheless present a resurrecting life-extension alternative.

For ongoing data on this subject, along with my and colleagues’ periodic protection, market analysis agency IDTechEx commonly publishes weblog posts on numerous battery expertise developments which I additionally commend to your inspection. I’ve no reference to the agency apart from being a contented client of their ongoing data output!

Drones as armaments

As a child, I used to be intrigued by the historical past of warfare. Not (at all) the maiming, killing and different destruction elements, thoughts you, as an alternative the gear and its underlying applied sciences, their use in conflicts, and their evolutions over time. Three associated developments that I repeatedly seen have been:

1. Applied sciences being launched in a single battle and subsequently optimized (or in different instances disbanded) primarily based on these preliminary experiences, with the “success tales” then reaching widespread use in subsequent conflicts
2. The oft-profound benefits that adopters of recent profitable warfare applied sciences (and gear and methods primarily based on them) gained over less-advanced adversaries who have been nonetheless using prior-generation approaches, and
3. That new expertise and gear breakthroughs typically quickly obsoleted prior-generation warfare strategies

Re level #1, off the highest of my head, there’s (with upfront apologies for any United States centricity within the examples that observe):

• Chemical warfare, thought of (and briefly experimented with) through the US Civil Struggle, with widespread adoption starting in World Struggle I (WWI)
• Airplanes and tanks, launched in WWI and extensively leveraged in WWII (and past)
• Radar (airplanes), sonar (submarines) and different digital surveillance, initially utilized in WWII with broader implementation in subsequent wars and different conflicts
• And RF and different electronics-based communications strategies, together with cryptography (and cracking), as soon as once more initiated in WWII

And to intently associated factors #2 and #3, two WWII examples come to thoughts:

• I nonetheless vividly recall studying as a child about how the Polish military strove, armed with nothing however horse cavalry, to defend in opposition to invading German armored brigades, though the veracity of not less than some elements of this propaganda-tainted story at the moment are in dispute.
• After which there was France’s Maginot Line, a pricey “line of concrete fortifications, obstacles and weapon installations constructed by France within the Thirties” ostensibly to discourage post-WWI aggression by Germany. It was “impervious to most types of assault” throughout the 2 international locations’ shared border, however the Germans as an alternative “invaded by way of the Low International locations in 1940, passing it to the north”. As Wikipedia additional explains, “The road, which was speculated to be absolutely prolonged additional in the direction of the west to keep away from such an incidence, was lastly scaled again in response to calls for from Belgium. Certainly, Belgium feared it could be sacrificed within the occasion of one other German invasion. The road has since turn into a metaphor for costly efforts that provide a false sense of safety.”

I repeatedly consider case research like these as I examine how the Ukrainian armed forces are, each within the air and sea, now utilizing progressive, typically client electronics-sourced approaches to defend in opposition to invading Russia and its (initially, not less than) legacy warfare methods. Airborne drones (extra usually: UAVs, or unmanned aerial autos) have been used for surveillance functions since not less than the Vietnam Struggle as alternate options to satellites, balloons, manned plane and the like. And starting with plane such because the mid-Nineties Predator, UAVs have been additionally in a position to carry and hearth missiles and different munitions. However such platforms weren’t solely massive and expensive, but additionally remotely managed, not autonomous to any notable diploma. They usually weren’t in and of themselves weapons.

That’s all modified in Ukraine (and elsewhere, for that matter) within the trendy period. Partly hamstrung by its allies’ constraints on what missiles and different weapons it was given entry to and the way and the place they may very well be used, Ukraine has broadened drones’ utilization past surveillance into innate weaponry, loading them up with explosives and sometimes flying them tons of of miles for subsequent detonation, together with all the best way to Moscow. Initially, Ukraine retrofit client drones sourced from elsewhere, but it surely now manufactures its personal UAVs in excessive volumes. In comparison with their Predator precursors, they’re compact, light-weight, low value and rugged. They’re more and more autonomous, partly to counteract Russian jamming of wi-fi management indicators coming from their distant operators. They will even act as flamethrowers. And because the picture proven firstly of this part suggests, they not solely fly however additionally float, a key think about Ukraine’s to-date success each in stopping a Russian blockade of the Black Sea and in attacking Russia’s fleet primarily based in Crimea.

AI (once more, and once more, and…)

AI has quickly grown past its technology-coverage origins and into the each day clickbait headlines and chyrons of even mainstream media retailers. So it’s most likely no shock that this explicit TLA (with “T” standing for “two” this time, versus the the standard) is an everyday presence in each my end-of-year and next-year-forecast writeups, together with loads of ongoing further AI protection in-between annually’s content material endpoints. A month in the past, for instance, I strove to persuade you that multimodal AI could be ascendant within the yr(s) to return. Twelve months in the past, I famous the growing significance of multimodal fashions’ massive language mannequin (LLM) precursors over the prior yr, and the month(-ish) earlier than that, I’d forecasted that generative AI could be a giant deal in 2023 and past. Lather, rinse and repeat.

What concerning the previous twelve months; what are the highlights? I may simply “write a guide” on simply this subject (as I admittedly nearly already did earlier re “Battery Transformations”). However with the three,000-word depend threshold looming, and at all times aware of Aalyia’s wrath (I child…possibly…), I’ll attempt to observe restraint in what follows. I’m not, for instance, going to dwell on OpenAI’s start-of-year administration chaos and ongoing key-employee-shedding, nor on copyright-infringement lawsuits introduced in opposition to it and its rivals by numerous content-rights house owners…or for that matter, on lawsuits introduced in opposition to it and its rivals (and companions) by different rivals. As a substitute, right here’s a few of what else caught my eye over the previous yr:

• Deep studying fashions have gotten extra bloated with the passage of time, regardless of floating point-to-integer conversion, quantization, sparsity and different methods for trimming their dimension. Amongst different points, this makes it more and more infeasible to run them natively (and solely) on edge gadgets similar to smartphones, safety cameras and (yikes!) autonomous autos. Think about (a theoretical case research, thoughts you) being unable to keep away from a collision as a result of your automotive’s deep studying mannequin is just too dinky to cowl all doable edge and nook instances and a cloud-housed complement couldn’t reply in time resulting from server processing and community latency-and-bandwidth induced delays…
• Because the fashions themselves develop, the quantity of processing horsepower (to not point out consumed energy) and time wanted to coach them will increase as effectively…exponentially so.
• Useful resource calls for for deep studying inference are additionally skyrocketing, particularly because the skilled fashions referenced turn into extra multimodal and in any other case advanced, to not point out the brand new information the inference course of is tasked with analyzing.
• And semiconductor provider NVIDIA right this moment stays the first supply of processing silicon for coaching, together with (to a lesser however nonetheless notable market section share diploma) inference. To the corporate’s credit score, a long time after kicking off its advocacy of general-purpose graphics processing (GPGPU) functions, its longstanding time, cash and headcount investments have borne big-time fruit for the corporate. That stated, rivals (inspired by clients aspiring for favorable multi-source availability and pricing outcomes) proceed their pursuit of the “Inexperienced Crew”.
• To my earlier “consumed energy” feedback, together with my even earlier “seemingly insatiable appetites of AI workload-processing information facilities” feedback, and as my colleague (and former boss) Invoice Schweber additionally just lately famous, “AI-driven datacenter vitality demand may increase 160 % over the subsequent two years, leaving 40 % of current services operationally constrained by energy availability,” to cite latest protection in The Register. In response to this looming and troubling state of affairs, in the previous couple of days alone I’ve come throughout information concerning Amazon (“Amazon AI Information Facilities To Double as Carbon Seize Machines”) and Meta (“Meta desires to make use of nuclear energy for its information facilities”). Loads of different latest examples exist. However will they arrive in time? And can they solely speed up right this moment’s already worrying international warming tempo within the course of?
• However, despite all of this spiraling “heavy lifting”, researchers proceed to conclude that AI nonetheless doesn’t have a coherent understanding of the world, to not point out that the ROI on ongoing investments in what AI can do could also be beginning to stage off (not less than to some observers, albeit not a universally held opinion).
• One ultimate opinion; deep studying fashions are seemingly already changing into commodities, a development aided partly by more and more succesful “open” choices (though simply what “open” means has no scarcity of related controversy). If I’m somebody like Amazon, Apple, Google, Meta or Microsoft, whose deep studying investments reap returns in related AI-based companies and whose fashions are “buried” inside these companies, this development isn’t so problematic. Conversely, nonetheless, for somebody whose core enterprise is in creating and licensing fashions to others, the long-term prognosis could also be much less optimistic, irrespective of how rosy (albeit unprofitably so) issues might at present appear to be. Heck, even AMD and NVIDIA are releasing open mannequin suites of their very own these days…

Auld Lang Syne

I’m scripting this in early December 2024. You’ll presumably be studying it someday in January 2025. I’ll cut up the distinction and wrap up by first wishing you all a Pleased New Yr!

As typical, I initially deliberate to cowl quite a lot of further matters on this piece, similar to (in no explicit order save for the way they got here out of my noggin):

• Matter and Thread’s misfires and lingering aspirations
• A lot mentioned (with success actuality to observe?) chiplets
• Plummeting-cost photo voltaic panels
• Iterative technology-related constraints on China (and that nation’s predictable responses), and
• Intel’s ongoing, deepening travails

However (additionally) as typical I ended up with extra issues that I wished to jot down about than I had an affordable wordcount finances to take action. Having now handed by way of 3,000 phrases, I’m going to restrain myself and wrap up, saving the extra matters (in addition to updates on those I’ve explored right here) for devoted weblog posts to return within the coming yr(s). Let me know your ideas on my top-topic alternatives, in addition to what your checklist would have appeared like, within the feedback!
