I keep running into that also. It's like the common mental model of a microcontroller froze around Y2K as a sort of headless VIC-20. I had an FAE, and a good one, from a major supplier tell me "you can't implement a filter" on a low-end micro that was roughly as powerful as an early nineties DSP.

A lot of 'em you just give 3.3V and a couple of bypass caps, and GCC will use the single-cycle hardware MAC (for M4 and above) if you just write the straight-forward C code and you can put it on there in 600ms with DFU. I'm a hobbyist, not an embedded wizard, but it really seems *pretty* good compared to what I understand about the old days. (Like I like retro stuff and during COVID I bought an old DSP56k dev board with a book about the assembly language but oh boy, oh dear)
