> researchers that's certainly one way to refer to Scott Alexander

Scott Alexander essentially provided editing and promotion for AI 2027 (and did a great job of it, I might add). Are you unaware of the actual researchers behind the forecasting/modelling work behind it, and you thought it was actually all done by a blogger? Or are you just being dismissive for fun?

tbh mostly dismissive of Scott Alexander for fun, couldn't quite help myself

Sigmoids may look like exponential growth at first, until they saturate. Early growth alone cannot distinguish between them.

Intelligence must be sigmoid of course, but it may not saturate until well past human intelligence.

Intelligence might be more like an optimization problem, fitting inputs to optimal outputs. Sometimes reality is simply too chaotic to model precisely so there is a limit to how good that optimization can be.

It would be like distance to the top of a mountain. Even if someone is 10x closer, they could still only be within arms reach.

Not so fast! Check this out https://github.com/googleapis/python-genai/issues/460 In my experience, you can only use Gemini structured outputs for the most trivial of schemas. No integer literals, no discriminated unions and many more paper cuts. So at least for me, it was completely unusable for what I do at work.

That's the level of coding I expect from a bunch of Python-only ML computer scientists, but still... wow. On the upside, they seem to have fixed it: https://blog.google/innovation-and-ai/technology/developers-...

Fixed some of the things, indeed. But don't let this blog post fool you. When using discriminated unions, Pydantic exports JSON schema with `oneOf` while the google-genai expects `anyOf` so that does not work out of the box. Also it still does not support basic stuff like when you have this in you Pydantic model: `foo: Literal[1, 3, 5]`

It's still far from what I'd expect should be supported.
