Agreed. All variable names should be single-letters as the Greek Gods intended :D
HappMacDonald··on Claude discovers a novel enzyme system with CRISPR-like repeats
The hardware miniaturization gains have finally dried up, though.

I am pretty certain that the current state of the art silicon feature size won't shrink again for at least another decade or two.

It normally takes about a decade to mature a tech which can create a smaller feature size into something commercially viable for mass production scale, and no further improvements have been in the pipeline for that long now.

So it's like the "next piece" indicator while playing Tetris is just blank.

Or, they care but they lack the vocabulary to express what they care about.

You can get a new laptop to run software A or competing software B.

You can pay $1000 for the laptop with 4GB of RAM, and software A either can't run on that or will act like pulling teeth, so that software requires you to upgrade to 16GB of RAM which will put you back another $2000.

Or you can run software B which will hum along perfectly smoothly on the original $1000 laptop.

(All of that of course simplifying right past "everyone runs every app 24/7 with five trillion browser tabs open")

Are you honestly suggesting that the end user doesn't care about having to throw exponentially more money at stuffing RAM into their PC just to make the game all their friends are playing online function?

Resource constraints have historically been a bastion of quality engineering, though. The relationship is not directly causal, but any time an engineer must not only solve a problem but _fit it within some kind of a budget_ vs having an unlimited budget, it forces them to slow down and think more carefully about what they are producing and how well it actually functions.

Ultimately it is an expression of anti-fragility: some minimal challenge must be met and conquered on many different axes of a production in order to help the full production itself mature to the best possible quality.

It is the same reason we exercise, the same reason that cars and toilets and so many products greatly increase in quality after emissions and usage and waste-related regulations get applied from above, etc.

The appreciation of the refining force of outside limitations is not about min-maxing, but it is at least partly about curbing the min-maxing of other concerns such as "ship the fastest garbage possible to move on to the next opportunity to repeat that process".

Why would you ask them to search for you if you knew they wouldn't get the same images you would get?

Claim: A vast majority of human-made clip art that involves flags as tertiary elements will fail to render them in a vexillologically perfect manner.

Can you delegate to the AI to use WordArt for you?

(One reason I ask is because it _might_ be nice to have more well trained AI gen _vector_ art options..)

Pay a lot for a human artist who just turns around and gens the output anyway? xD
HappMacDonald··on I built non-autoregressive decision models with RL a year ago
I would rate using LLM for tasks more specific ML can handle as a lot like using one's smartphone to snap photos, listen to music, set alarms, and play video games in preference to carrying around a fun cam, ipod, watch, and switch 2 everywhere.

For those who need to dive really deep into each specific avenue and squeeze maximal quality out, the photographers will be packing DSLRs and intense gamers will wait til they get home to strap into a PS5 or a gaming rig or VR or whatever.

But "can get 90% of anyone's needs met in this field, and can do the same in dozens or hundreds of other fields simultaneously" will remain the killer solution for anyone with lots needs that each have bounded depth.

> If your axioms are wrong then of course your logic will be wrong.

Equally, even if your axioms are right your logical execution can still fail.

Neither individual humans nor LLMs get either of those steps right as a default. Just as LLMs must use hacky CoT and other systems of error checking and correcting to even begin to emulate reasoning, humans must do the same thing.

We are apes. We are driven by emotion and solve problems either when we are forced to or as a sport. We did create the ultimate automata of logical execution: the deterministic von Neumann Machine, but a human brain in no way reflects that operation. Nor, as you have observed, does an LLM despite using one as its substrate.

HappMacDonald··on Inverse Kinematics and Foot Locking
I would rate anything that is a sufficiently immersion-challenging distraction to be a problem.

Would the game be more fun if we just chop off all the character's legs and make them float like apparitions instead? That needn't actually change the nuts and bolts game mechanics, but it would be less realistic and/or require big story changes like "it turns out all these characters are ghosts" or something. Same with having every character float through walls instead of walk to a door to enter/exit so that we can save on pathfinding logic.

People are very accustomed to seeing other footed beings have their feet "locked" to the ground by the weight of their body as they stand, walk, or run. Having every character constantly look as though they are suspended by the waist with legs just dangling arbitrarily is something a lot of people are going to find immersion-breaking: and it's one of those issues where the more realistic detail you have in other areas the bigger this remaining issue stands out. Minecraft/Roblox/stick figure characters can probably get away with a lot less care on this detail than TF2-or-above realistic characters can.

Well obviously the real solution is for the owner of the company to

1. Fire everyone else

2. prompt the AI "make me more money than you cost" (that's a short prompt, innit?)

3. Retire to Aruba

Nobody is hired for a job if the person hiring thinks that the employee will murder them. So I guess that makes the most salient job description "refraining from murdering your boss"?

Or it might be that any baseline expectation which applies to 99.99% of all employment (I don't need Kevorkian giving me the side eye..) fails to be a good way to differentiate one kind of employment from the next or describing how and why people choose a specific kind of employment

Given that the abundance will be predictably hoarded by those in power — leaving everyone else even fewer table scraps than we already get — should however remain a concern.

After all, its not like some benevolent super-AGI will be deciding who the spoils get divided amongst, they will remain tools to perpetuate and intensify every incumbent power imbalance.

HappMacDonald··on Large language models develop novel social biases through adaptive exploration
While that may be true in reality no such externality consequences appear to be baked into the game theory of the experiment.

It's like having people or neural networks choose door 1 from door 2 without clear advantage to either of them and without making it clear that one door somehow represents "donating blood" while the other represents "kicking puppies".

HappMacDonald··on Bug Blindness
On the other end of that spectrum I cannot _stand_ back button on the mouse and always disable the feature immediately because it is often too easy for me to click those fiddly side buttons without meaning to (either while grabbing or while re-adjusting my hand position on the mouse)

So I usually only map middle click to such a button, as that button is at least 90% of the time relatively safe to accidentally trigger.

There exists a floor to how "idiot-proof" Motor vehicles are since they do require a skill test and a licensing protocol to legally operate that do weed out some number of humans not competent enough to operate them (and even beyond that insurance qualifications can weed out some more: crash or commit infractions too much and you lose and/or get priced out of your ability to legally drive). And rightly so due to the unique hazards that they pose: but for want of those things one may easily still have to try to support their software for users incapable of gainfully handling a motor vehicle.

Automobiles and the international road network have also had well over a century to standardize themselves over a glacially slowly changing set of expectations while we're writing drivers for 400GBE chipsets that only got invented last Tuesday and building agent management harnesses for styles of neural networks that literally weren't even a twinkle in the milk-man's eye yet as recently as fidget spinners being in style.

There's a big difference between "letting the facts guide the path" and tilting at strawmen built out of straw nobody else even brought into the discussion.

If you'd like to make the point that "cost of panels" can be misleading when supporting components and interconnects begin to take up the lion's share of costs then that sounds like a noble thing to remind folk of, but ideally not as a segway into shilling more fracking which includes untold environmental costs as externalities.

I have been lead to believe that blue scrub jays have a lot of different vocalizations but the only sounds I've caught out of them over the past 15ish years of paying attention have been the raucous shouting shrieks they seem so fond of doing. I perceive this as their species equivalent of cursing xD
