One comment on this being a good prediction of what we see in 2020. Yes, it was obvious in the 1990s that the web was going to be a platform for apps. That was why browsers were such a big piece of the antitrust case against Microsoft. The charge made against Microsoft was that it was better to write to a browser API than to the Windows API, and that's why Microsoft did what it could to kill browser competition with a Windows-only browser. That way, even if you wrote to the browser API, you were still writing your app for Windows.

Java transformed the way people thought about these things. Microsoft didn't like Java and they didn't like competing browsers because they were reasonable platforms.
