> Is there something like a Turing test for AGI?

There is the "Economic Turing Test", you let it find a job and earn money for itself. If it can do that reliably, across a wide range of jobs, that should fit most definitions of AGI.

They are desperately, desperately trying to make a name for themselves as the lab that first created AGI, because Anthropic's IPO is just around the corner.

The “I” alone is already not well-defined. That’s why.

It's not easy to test as there is no formal definition or formal criteria for AGI, only exclusionary criteria like "not X". That's why he phrased it that way, he's saying it's going to be clear with hindsight once we have a better understanding of things that this time and/or this model will be the inflection point of AGI.
