It isn't.

"AI is a bubble" and "AI is going to replace all human jobs" is, essentially, the two extremes I'm seeing. AI replacing some jobs (even if partially) and the bubble-ness of the boom are both things that exist on a line between two points. Both can be partially true and exist anywhere on the line between true and false.

No jobs replaced<-------------------------------------->All jobs replaced

Bubble crashes the economy and we all end up dead in a ditch from famine<---------------------------------------->We all end up super rich in the post scarcity economy

It is completely fallacious.

For one, in higher dimensions, most of the volume of a hypersphere is concentrated near the border.

Secondly, and it is somewhat related, you are implicitly assuming some sort of convexity argument (X is maybe true, Y is maybe true, 0.5X + 0.5 Y is maybe true). Why?

I agree there is a large continuum of possibilities, but that does not mean that something in the middle is more likely, that is the fallacious step in the reasoning.
