I do find it odd that little is being said about this part of Tim's post:

In fact I personally believe that Java’s share of enterprise software will decline, but not in favor of anything from Redmond. I think that dynamic languages (Python and friends), particularly in conjunction with Test-Driven Development, are looking more like winners all the time. They generally are cheaper to program in, run just as fast, and have fewer bugs; what’s not to like? There is one huge niche that the strongly-typed statically-compiled languages are never going to be driven out of, but I’ll save writing about that for later because I’ve got a major skunkworks in mind.
