Why is this here?

Writing device drivers isn't sexy like TheLatestFramework™ but are an important part of computing.

Because the lab tutorials are using Rust and the device drivers are "Written in Rust™" which is trendy in 2026.

This is the only explanation, but clearly almost no-one is interested in writing their own device drivers in 2026 after more than 5 hours of this post with less than 10 comments.
