Using Claude Code to modernize a 25-year-old kernel driver

I had a suspicion AI would lower the barrier to entry for kernel hacking. Glad to see it's true. We could soon see much wider support for embedded/ARM hardware. Perhaps even completely new stripped-down OSes for smart devices.

Nothing was lowered because there was no barrier:

> As a giant caveat, I should note that I have a small bit of prior experience working with kernel modules, and a good amount of experience with C in general

But yeah, the dream of new OSes is sweet...

I'd bet a couple dollars that it'd take a week for someone who hasn't hacked on the kernel at all, but knows some C and two weeks for someone who doesn't even know C but is a proficient programmer. This would previously take months.

We're talking about an order of magnitude quicker onboarding. This is absolutely massive.
