You don't have to fully vibe code it. Most of this stuff doesn't take massive brains, it is just super tedious - especially the reverse engineering. I've never really had the patience for that (except one USB devices that I did reverse engineer when I was younger). AI really helps with the tedium.

What make you think it is vibe coded? There is no mention of genAI being used, and the methodology looks more consistent with hand-written code he actually understands.

If it is coded in safe Rust, why not ?
