Nope. There's a lot of unscientific intellectualism out there. I don't see a lot of intellectual depth in the communities springing up around AI use — I had vibecoding in particular in mind, and Fernando's blog post directly addresses mathematics.

I don't understand the contrast you're drawing. Harness design and benchmarking are major aspects of vibe coding (and solving math problems with LLMs, for that matter); I would go so far as to say harness design and benchmarking are the more intellectually serious aspects of vibecoding. Fernando is definitely aware of them as well. These just aren't meaningful substitutes for the intellectual work being diminished.
