If you need a specific specialist degree (like a PhD in linear algebra), then that's just the professional baseline knowledge I already mentioned.
When I last read Strang's, my course included a lot of spectral theory that was decidedly not introductory regardless of what the title says. Either way, the point is that most non-specialist practitioners don't need that. How often have you truly run into determinants mod N or stochastic matrices in real life?
It sounds like our linear algebra classes were somewhat different though. No one received an A in mine. I had one of 3-4 B's.
Never ran into modular determinants IRL but stochastic matrices are pretty common in many jobs - that said honestly anyone that's actually good at linear algebra and dev work has some pretty good options in many fields so considering it as a baseline unremarkable requirement is uncalled for, I agree.
