Silverlight was an obvious bust from the beginning, no one with longevity in mind jumped on that ship and fought against anyone pitching it at the time (mostly inexperienced devs, sales people, and tech companies looking to make a quick buck). Anything plug-in based was already on the chopping block by the time it came out. Blazor WASM is, at least, as safe a bet as any popular JS framework. If .NET was still a Windows only thing, I'd stick with the JS frameworks, but now that it's cross platform, I've got no problem choosing Blazor over any other UI framework that just as easily might need a full rewrite in a few years.
