The speaker proposes token spend divided by human salary spend as a useful AI-investment metric, estimating a typical ratio near 0.1, a potentially safe level up to 1, and possible trouble above 1.5.

“I think, uh, a good metric is basically what is your ratio of token spend to human spend, and it's r- like, for a lot of people, it's maybe 0.1... tokens to, to one human salary.”

“And, uh, you know, y-you can probably go up to one pretty safely, and if you're over 1.5, you're probably in trouble. [laughs] Something like that.”
