I was able to get Claude to write an embedded Rust driver for an unsupported epaper screen in a couple of hours by providing it with the spec and some existing C drivers. It’s still not as fast as the arduino versions, but it let me make progress in a project that I’d been stuck on for months.

Reverse engineering seems like an AI sweet spot.

In general I've been really happy to leverage Claude to quickly build software that only I use. It fits my needs exactly and I don't have to worry so much about how others will use it, if it is generalized enough, if the documentation is up to date, etc.

It's kind of nice.
