The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 7 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Chubuk: AI cannot reason to breakthrough superconductors from training data alone
“I think it's still true that it would be difficult to just reason your way into a much better superconductor. I actually would guess that there's a law out there that we haven't discovered yet that says that you can't just look at your training set that's diff…”
Chubuk: GPU compute and training costs drove Periodic Labs' $300M seed
“We are going to train LLMs, we are going to use GPUs to run simulations, so that does end up being a large part of the cost. Yeah, it's funny, like, before, you know, if you asked me this question 10 years ago, I would have thought that the biggest part of the…”
Chubuk: Superconductivity moonshot will yield independently valuable automated lab capabilities
“To discover a exciting superconductor, we probably have to develop so many capabilities on the way there that's By themselves very useful. For example, automated synthesis, automated characterization, being able to model or predict high temperature superconduc…”
Chubuk: High-throughput liquid- and powder-mixing robots have become commoditized
“These robots, they became quite commoditized, actually, just mixing powders, or mixing liquids, and then sending it to characterization.”
Chubuk: Periodic Labs is not prioritizing full wet-lab automation
“You know, we, we're not really prioritizing full automation anyway, so if we get better results with humans doing part of it, that's great.”
Chubuk: Periodic Labs aims to achieve automated materials characterization soon
“I think one thing that isn't as advanced right now, but we feel like we can do pretty soon, is automated characterization itself. So, you mix powders, you put it in the, some characterization tool, you get the result out, What is the actual output? I think tha…”
Chubuk: Minimal physical experiments carry huge information value by validating synthetic simulations
“What's interesting about scientific data is it's not just a few bits or numbers, right? Like, for example, there are certain experiments you can run where the result you get from it is just, say, three floating point numbers. But the implications of those coul…”
