Between Delphi, C#, and TypeScript the man has already had a storied and impactful career.
I’d love to see him take lessons learned from C# for a language designed for WASM from the get go.
AssemblyScript is already quite ahead regarding WASM support.
In that video he says that it’s not a suitable target for TypeScript to compile to because WebAssembly doesn’t have a garbage collector. They’d have to basically implement an entire JavaScript engine in WebAssembly which would be pointless.
He gives some examples of things it could be good for, which are all CPU intensive things like image processing and video games, but he doesn’t seem to think it’s really suitable for making normal web apps.
