Most hardware drivers are simpler than people expect. The hardware is usually designed to do the sensible thing in a straightforward way, and you're just translating what the OS wants into a bunch of bits you need to write to the right hardware register.

On the flip side, the perceived barrier is high. Most folks don't have an intuitive sense of how the kernel or "bare metal" environment differs from userland. How do you allocate memory? Can you just printf() a debug message? How to debug if it freezes or crashes? All of these questions have pretty straightforward answers, but it means you need to set aside time to learn.

So, I wouldn't downplay the value of AI for the same reason I wouldn't downplay it with normal coding. It doesn't need to do anything clever to be useful.

That said, for the same reasonss, it's harder to set up a good agent loop here, and the quality standard you're aiming for must be much higher than with a web app, because the failure mode isn't a JavaScript error, but possibly a hard hang.

Harder, but not impossible. You 3d print a jig for a solenoid and a relay so you can warm/cold reboot the laptop, get a pizerow setup and configured to be a keyboard you can control over SSH, a webcam watching the screen, a hardwired Ethernet port, a second computer to manipulate the Device Under Test (aka the MacBook/laptop with a missing whatever driver). Even though waiting on Claude Code doesn't hit flow state if you've only got one project going, setting things up so it can run with it is still fun, for specific and rather nerdy definitions of fun.
