Just talking to some InfoSec guys at a party on Saturday at noon, they couldn't drink because they were headed back into work. It's not just PHP, it's everything. They were "joking" about changing professions, because it sucks and it's getting worse. They can't even use frontier models, just use open weights to not get degraded.

Is it the EGC lack of disclosure rules (for pre-Unicorns), the fractional share ownership? How is the JOBS Act what drove change?

There's lots of stories of non-anthropomorphic intelligences that are human friendly. Sometimes humans do bad things with them, but they're not evil. "Shall we play a game?", HAL9000, Phaecian ships of antiquity, or those of the Culture. Androids seem uniquely unfortunate, perhaps as another poster noted, because of the stories of golem.

Well, yes stories is basically what LLMs are, and they're optimized to be stories that humans like. I fully expect to be entertained to death before the droid wars, but if there is a horribly misaligned LLM, I fully expect it to be created by the guy who thinks bipedal anthropomorphic robots are a good idea.

Wait, it fell from 140% growth to 45% growth and that's a good thing? If they fall to 15% growth in Q4, will that be even better? Where are we supposed to be on the adoption curve?

What percentage of people are neither of the simple common XY nor XX chromosomes? It's about as many people as there are with red hair. If you don't include chimerics it's about 0.25-1.7%, if you do include twin chimerics it's 8%, not including mothers micro-chimerism.

Probably shouldn't be having those Kenyans (Kalenjin) competing in marathons either. Completely unfair advantage.

All models are wrong, some are useful.

Note that rubies are also color changing (thermochromatic)! The absorption band gap of ruby (well, really the Cr d-shell band) expands to longer wave lengths at high temp and contracts at low temperatures so that it is light orange ~77K or -200C and turns black (IR) ~400C.

Yeah, I don't understand where this is coming from. If you're not teaching the math, what are you even doing? Maybe it's from pop-sci books or something where they're really selling woo rather than comprehension?

My books went from 2 slit experiments, to particle in a box (1d and then 2d harmonic oscillators) with tunneling, and then the Hydrogen atom potential with electron orbitals as an extension, to perturbations for He, to Hartree-Fock and Born-Oppenheimer for large atoms and molecular models. Learning the <bra/ket> formalism can be useful for thinking about it, but it has to be motivated by the math.

I guess black body and scattering were pretty early too as motivation for the developments (as they historically were). Whereas EPR/Bell, Decoherence, and "Interpretations" were mostly discussed as interesting flavor and philosophical arguments.

It's what plants crave!

To add a bit more almost off topic substance from the enshitification of human work. I really do think the idea of hooking these "AI" models up to humanoid robots is a bad idea not for all the mundane reasons, but just because "alignment" seems impossible. All of the world's stories about humanoid robots basically involve them attacking humans and behaving in nefarious destructive ways. It's fundamentally embedded in the models, and there's no reason post training would pull it out, because it's basically in the key value vector meaning "malicious human destroyer". Even to find counter examples like C3PO, Daneel Olivaw, Data, or Wall-ee they come after droid/robot driven wars and apocolypses. It seems unwise.

They'll turn off your lifesaving drone internet access as well.

Actually, yes guidelines are actually that any prior statin prescription removes the need for CAC measurements. That includes those who are discovered to have statin intolerance, and thus requires out-of-pocket payment for any CAC.

I think the challenge here is that other than a CCTA there's no good way to estimate individual (as opposed to hereditary) ASCVD risk. Sure LDL, ApoB, Lp(a), and BP, are statistical proxies, but tell you little about the individual risk. CAC isn't much better, but if you've been taking EPA and VitK2 you have a much higher chance of more stable plaques, which are also more visible on CAC without much larger X-ray exposure and iodine contrast effects.

You can't optimize the sweet sweet ad cash by just being a journalist! The need for a commercial tie-in zinger twist is ingrained now.

To steel man the argument, I think that there really is a Moore's Cliff coming. I don't think that resolution is going to matter as much, although process/design knowledge will still be a huge barrier. I don't see even 10A being as big a node as 14A or 2nm. Too many things fall apart all at once, and the cyclical nature of semi will raise it's bloody head above the industry as the AI trade bursts. So many $10Bs will be spent and margins will plummet... again, just in time for China to catch up.

Already, the big capabilities are becoming multi-layer/die integration. Whether it's BSPDN, stacked die, optical interconnects, etc it won't be as simple as Denard scaling. It will be dependent on experience and supply chains, which are harder to transfer than equipment or IP.

I do think the market for inference will drive a lot of innovation, and a lot of that will be at larger nodes. A single reticle die masked ROM with CIM can do 7B at 6nm. At 2-3nm you can do 27-32B which is a single expert or router. At that point there's not much reason to shrink for AI since it's mostly 1-hot die per token (except for the router). Update the parameters every 3-6mo when a new frontier comes out, and take the cost/power savings to the bank.

Go bet on it @=^D It's not speculation, it's what they sell to the world and build processors for globally available Huawei/Honor phones. It's not a secret.

If they had a solution to get to >90% yields on sub 5nm they'd be doing it now. They don't, even the 7-10nm isn't there. Best hope is they get to buy the entire world's supply of EUV in 2027, then they install all of them, then they bring them up, then they build processes around them and make masks, then they ramp the yield on 3-4nm by copying exact TSMC.

The hilarious thing is that TSMC couldn't do this at a new fab in Taiwan, with full access to equipment, supply chain, and people. So, nope.
