You're right, I'm being extremely charitable to Java and Python. As you say, there was a Java browser (HotJava) in the early days of browsers, and there was a Python browser once called Grail, but neither one was even close to Firefox/Chrome/Safari. I think you _could_ write a Firefox clone in Java, and in Python too (though a Python Firefox clone would be perhaps too slow to use). My point was that I don't think you could even write such a beast in Forth (or, more accurately, in Forth using the extreme-Forth approach described in the article; maybe it would be possible in ANS Forth). You need the abstraction layers or the problem is unmanageable.
