This reads persuasively, but the problem is that the same arguments have been made consistently since as long as I can remember. When I was an undergraduate, people were saying much the same thing, and almost nothing has really changed. I myself have always had both Windows and Linux (and occasionally OSX) boxen around to help me do what I need to do - so what's right in front of me doesn't seem so one-dimensional as what PG writes about. I've also been in and out of some radically different industries (for example, appdev consulting vs aerospace & defense), and it seems pretty obvious to me that "best tool for the job" is the future and it always has been. That means there will always be a place for Windows and BSD/Linux+derivatives (I throw OSX in this bucket), and there will always be engineers of many stripes using each one (or multiples). I mean, seriously: even Git - which really does seem to have utterly won the VCS wars from a certain perspective, is still just one of many in reality. Lots of people use Perforce. Legion upon legion still use TFS. BitKeeper is still kicking around. Subversion still has substantial usership. Even CVS is still around. Pretty much the only VCS technology that has truly been defeated is RCS/SCCS, and probably only because they never figured out how to handle directories or else they'd still be around too. That's why I find these kinds of prognostications to be very silly (although fertile ground for gathering up fake internet points and/or blog readership).
