# Quote of the Week

<!-- QOTW goes here -->
> While working on these userspace Mesa changes today, I did not hit a single GPU kernel driver bug. Not. A. Single. Bug.
>
> This is thanks to Lina's phenomenal efforts. She took a gamble writing the kernel driver in Rust, knowing it would take longer to get to the first triangle but believing it would make for a more robust driver in the end. She was right.
>
> A few months of Lina's Rust development has produced a more stable driver than years of development in C on certain mainline Linux GPU kernel drivers.
>
> I think... I think I have Rust envy 🦀
>
> ....Or maybe just Lina envy 😊
