You'd be surprised. People even do bit-banging now (could you imagine bit-banging a VGA port directly in the past?). > Modern hardware isn't usable at that level. Is something like VC4 GPU modern enough? People do work with it on a very low level, thanks to the open specs. See this for example: https://github.com/mn416/QPULib https://github.com/mn416/QPULib Actually, all the modern GPUs are getting simpler and more unifirm, so it's getting easier to hack them on a low level.
