I mean, I benefited massively from reading Vol 1 of TAOCP and understanding Knuth's new assembly. Like, it hasn't been directly useful but I now have a deeper understanding of how my code actually executes, which has helped me contextualise performance problems.
So, I guess that I'm with the OP on this (this may change if we can figure out automated verification for software, at which point I'd be happy to mediate most things through an LLM with tools).
