IDK why Google took so long, Google is slow in a lot of areas, but Chrome has ran on ARM for years on other platforms (macOS, Android, etc.) so maybe they just forgot about Windows.
Who develops in .NET???? Are you kidding me? millions of people.

Even if you can only be bothered to learn scripting languages like JS or TS, React Native, Electron, Flutter, etc. have had ARM support for Windows for years now. Hell you can use WASM with LLVM and output Windows ARM for crying out loud.
I know some of you can't fathom this, but in the last 5 years every major language and platform our there has added native ARM support. You might as well get used to the idea that it's going to compete with x64 in every area.
