There's a kind of scam that some in the AI industry have foisted on others. The scam is "this is so good, it's going to destroy us. Therefore, we need regulation to prevent Roko's Basilisk or Skynet." LLMs have not gotten better in any significant degree. We have the illusion that they have because LLM companies keep adding shims that, for example, use Python libraries to correctly solve math problems or use an actual search engine on your behalf.
LLM development of new abilities has stagnated. Instead, the innovation seems to be in making models that don't require absurd power draws to run. (Deep Seek being a very notable, very recent example.)
I watched this video all the way through hoping they would turn things around but it's just the same fluff for a new audience.
