I think the video was ok, but the real highlight was learning about Raph Levien's work. His blog is a real gold mine about UI and GPU. He is the one behind Runebender and Xi editor.
Most of his work is in Rust. I never tried Rust but the people I admire don't like it. It might be worth it to have a look anyway.
I'm sure his blog will come in handy.
