that's an inaccurate characterization on #1. he's not saying ai risk is _all_ hype to boost valuations, but that it's misused to serve purposes other than warning.
What's "exponential" about AI development? Model parameter counts? Anthropic doesn't publish those for their own models, last I checked. Datacenter buildouts? Water consumption per request? There just isn't enough evidence that AI smarts is growing all that much, once you account for the scaling of inputs. That's what OP probably means by "nonsensical hype".
> It’s all just nonsensical hype
And he’s referring to completely real and reasonable warnings in anthropic blog posts about the exponential rate of AI development.
