Will Blazor make it? Perhaps but there are no jobs.
Will they rewrite VS Code in C# WASM? Never, Electron and Typescript work beautifully for millions of developers daily.
Chrome, the browser that won, will remain a Javascrpt friendly stack.
Of course there are not many jobs YET, server-side Blazor launched with .NET Core 3.0 only this September, while client-side Blazor is still in preview and will launch in May 2020, if all goes according to plan.
It is possible to host Blazor on Electron for desktop apps:
However, they haven't stopped there:
It does away with Chromium and Node for significant download size and memory footprint savings.
The newer IEs were arguably much better than older ones, while Edge was better still and now there is Chromium based Edge, so nothing left to complain about.
One of the main selling points of Node was a relative speed advantage: no longer true. Another was enabling same language development across front- and backend while others didn't: also, no longer true.
Hell, Python is most popular now and it's a slow, niche language, only ideal for ML/AI. Already for webapps there are many alternatives that are far better and for game development you can forget about it.
Oh yes, some people hate and will hate MSFT no matter what, and that has nothing to do with the quality of .NET Core/Blazor.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
