>That's because Rust GUI people are like Lispers and functional programmers — too obsessed with doing things correctly "from first principles" and "purity".

That's... entirely wrong and not necessary to paint swathes of developers like.

Rust has numerous solutions for native GUIs. People ship apps with those stacks. Rust also has things like Tauri for when you don't want to deal with differences across platforms.

Just because there's not one blessed solution doesn't mean it's not possible to write UIs in Rust today. ;P
