I'm finishing my bachelor's degree in radio electronics and instrument engineering. I've been using AI models to help me understand various concepts, but I want to say that, for now, they aren't ready for serious development.

What makes you think that? They're great at reading datasheets and creating schematics in my experience. Layout I've been doing myself though, with the AI evaluating. I'll eventually delegate that as well. For schematics I use Skidl and some custom binding generators.
