MongoDB was once backed up by adoption across the industry. Or for a more recent example, blockchain took off like wildfire across the industry before ultimately fizzling out in all but the most niche applications.

Not saying this trend will do the same, just that the industry adopting something doesn't guarantee its success.

I don’t think those are really comparable. The blockchain was trendy hype, relatively few companies actually adopted it. Where did Netflix use the blockchain? Google?

By comparison almost all tech companies I know have leaned heavily into AI.

leaned heavily = purchases subscription to claude not changed processes around ai.
