Or you might be using the presentism fallacy. After all, we keep reinventing LISP and it is from the 1950s. "Put it in the browser" is a strange thing to do.

Or you might be using the presentism fallacy. After all, we keep reinventing LISP and it is from the 1950s. "Put it in the browser" is a strange thing to do. A browser isn't really a VM for running applications; it's a document renderer. Coupling a browser with an operating system is also a strange thing to do. Yet these all occupied people's minds for a long time. Roughly only 40% of my computer use is on the Web at all. And much of that in on fora that could use a transport other than HTTP. Applications are not really documents.
