The decision to found Anthropic to compete with OpenAI's then concentration of SOTA LLM AI researchers, and then achieving/surpassing parity with OpenAI is pretty much directly responsible for creating the current capabilities arms race.
Google has shown they are not motivated at all to push the bigger and bigger SOTA frontier with Mythos-type super models. Even OpenAI isn't really even trying to surpass Anthropic at the top of the market, preferring to keep pace in benchmarks but at lower costs to serve. Anthropic with Mythos is now more or less alone in aggressively pushing the ceiling for the most "super-intelligent" models current computing can support.
It has made them and their investors a gigantic pile of money, but we're really supposed to believe their contribution to that arms race (which they now describe as a threat to humanity) has always been completely altruistic and that their corporate structure inherently makes self-interested decision making impossible?
If you've read enough lesswrong, this won't be new to you. The strategy always was "become the most capable model lab so that you have leverage to control AI development."
