Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.
This is not debate club. Unless it’s amusing debate.

oh hey, we're back to "deepmind models dreamed up some totally novel structures!", but proteins this time! news!
do we want to start a betting pool for how long it'll take 'em to walk this back too?
it’s weird how they’re pumping this specific bullshit out now that a common talking point is “well you can’t say you hate AI, because the non-generative bits do actually useful things like protein folding”, as if any of us were the ones who chose to market this shit as AI, and also as if previous AI booms weren’t absolutely fucking turgid with grifts too
I suspect it’s a bit of a tell that upcoming hype cycles will be focused on biotech. Not that any of these people writing checks have any more of a clue about biotech than they do about computers.
sounds to me a bit like crypto gaming, as in techbros trying to insert themselves as middlemen in a place that already has money, because they realized that they can't turn profit on their own
That was the hype cycle before crypto - you'll see companies that pivoted from biotech to crypto to AI.
given the semi-known depth of google-lawyer-layering, I suspect this presser got put together a few weeks prior
not that I'm gonna miss an opportunity to enjoy it landing when it does, mind you
You think wood glue in your pizza sauce is great? Try prions!
Haven't read the whole thing but I do chuckle at this part from the synopsis of the white paper:
And a corresponding anti-sneer from Yud (xcancel.com):
Now medium-throughput is not a commonly defined term, but it's what DeepMind seems to call 96-well testing, which wikipedia just calls the smallest size of high-throughput screening—but I guess that sounds less impressive in a synopsis.
Which as I understand it basically boils down to "Hundreds of tests! But Once!".
Does 100 count as one or many iterations?
Also was all of this not guided by the researchers and not from-first-principles-analyzing-only-3-frames-of-the-video-of-a-falling-apple-and-deducing-the-whole-of-physics path so espoused by Yud?
Also does the paper not claim success for 7 proteins and failure for 1, making it maybe a tad early for claiming I-told-you-so?
Also real-life-complexity-of-myriads-and-myriads-of-protein-and-unforeseen-interactions?
that sound you hear is me pressing X to doubt
Yud in the replies:
"I am so Alpha that the rest of you do not even qualify as Epsilon-Minus Semi-Morons"
Yud:
Not that curious, apparently
i suspect - i don't know, but suspect - that it's really leveraging all known protein structures ingested by google and it's cribbing bits from what is known, like alphafold does to a degree. i'm not sure how similar are these proteins to something else, or if known interacting proteins have been sequences and/or have had their xrds taken, or if there are many antibodies with known sequences that alphaproteo can crib from, but some of these target proteins have these. actual biologist would have to weigh in. i understand that they make up to 96 candidate proteins, then they test it, but most of the time less and sometimes down to a few, which suggests there are some constraints. (yes this counts as one iteration, they're just taking low tens to 96 shots at it.) is google running out of compute? also, they're using real life xrd structures of target proteins, which means that 1. they're not using alphafold to get these initial target structures, and 2. this is a mildly serious limitation for any new target. and yeah if you're wondering there are antibodies against that one failed target, and more than one, and not only just as research tools but as approved pharmaceuticals
i'm tired boss
wait that's just antibodies with extra steps
living things literally are just fuzzing it until something sticks and it works
but but proteins! surely they've got it right this time! /s
(I wondered what you'd say when I saw this. I can only imagine how exhausting)
i'm not done with the last one, i've already collected some footnotes but not enough to my liking
