  Right, a lot of questions that are frankly outside the scope of their specific work, since it depends on what the general ‘market’ is for used batteries today and if there’s any opportunity cost associated with the process (e.g. you can get the lithium, but you somehow make retrieving other materials tough.

  But yeah, if the $13.17 figure is, say, $3.17 raw lithium and extraction and $10 of ‘processing’, then the cost of spent batteries would have to be less than $0.77/kg by lithium content to be break-even.

  I’m hopeful that even nearly break even is enough to move the needle, but companies love taking advantage of cheaping out by inflicting externalized costs on the environment…

  Note when the article made the comparison, it seemingly sourced the comparative figure independently, not the scientists. So the scientists may be in good faith describing ‘incremental cost to take presumed existing battery material and recover lithium from it’ and article trying it’s best but not thinking things through presents "number that would implicitly include processing, but also cost of acquiring the raw material as well’. So no one may be trying to ‘hide’ something, but still the comparison is somewhat flawed.

  Just seeing how even if everything is being honestly presented, we may still be in a position where mined lithium is still cheaper than recycled even as all the figures suggest that shouldn’t be the case at face value.

  Question is does that $12.70/kg figure include sourcing the spent batteries?

  Great news, but would be curious to know if the figures are apples to apples, or if one of them excludes cost of the raw material.

  Oh the CS job market may just be more persistently toast. Yes there have been layoffs attributed to AI, however I think a lot of those businesses were kind of itching to do those layoffs anyway. There was way overhiring in the security in general, plus when the AI bubble pops it’ll drag the test if the tech sector with it.

  AGI might be just around the corner, or it might be indefinitely far off, but either way I don’t think “just more LLM” is going to get there, and that seems to be all the AI industry is really equipped to handle at the moment.

  Ironically, getting to AGI might take a bubble pop to stop the current LLM architectures from just sucking up all the resources to let other approaches breathe a little.

  More practically, I’d have expected to see more engaged robotics, but it seems all the money is being spent on pure online AI approaches.

  Seemed a likely outcome. On the way to being late, there were stories where basically they spent ungodly amounts of money in an attempt and then scrapped it because it wasn’t actually any better. And that this happened multiple times.

  So if they were truly stuck, what to do? They could admit they were stuck, and watch the economic collapse as investors realize they were mistaken on how far along the technology curve things were, or they could market the hell out of GPT-5 and pretend it’s amazing and hope enough suckers and latecomers to LLM buy into that narrative that it carries through. Like Sam Altman acting ‘scared’ of what GPT-5 is going to be, “what have we done?” in a very melodramatic way like he’s Oppenheimer or something, likening it to the Death Star (all in all, a very ‘wtf’ situation, if it were really as dangerous as you say, you seem awfully eager to get it going).

  So we have an incremental iteration with some good, some bad, and perhaps overall better, but in the context of the ungodly investment in the LLM sector, it’s way way less than would should reasonably expect.

  Yeah, it was the whole point.

  When Trump first said that, I wondered why the hell he’s talking about Musk asking for a position title that never existed, and then he tweeted out some BS AI gen of him with the title ‘DOGE’ on a nameplate in front of him.

  He basically is a 13 year old who never grew up.
