You can say that, but at the same time, whenever people complain about technology changing, leaving them behind, they usually mean tech by Microsoft.
The reason Java and JavaFX survived is that they went Open Source, with a large FOSS ecosystem, targetting FOSS operating systems as well, all while there still was interest. And their maintenance and evolution continued. Adobe RIA and Flash were proprietary platforms, just like Silverlight.
In fairness, projects that survive tend to be FOSS, and AFAIK, .NET Blazor is open source. OTOH, the .NET ecosystem tends to prefer Microsoft's solutions, with alternatives languishing, they basically killed Xamarin's projects, and they have had several noteworthy conflicts with the FOSS community. So the jury is still out on whether Microsoft's projects can escape the deprecation curse.

The lesson here, for all, if you want for your knowledge and work to stay relevant, look towards Open-Source platforms and open standards. If seeking stability, the older, the better, actually. FOSS platforms age like fine wine.
