Loyalties are cheap on the internet. You can say "no one cares about X". Just look at all the companies that switch between AWS and Azure these days whenever one or the other has an outage. Microsoft is making aggressive moves now.

.NET is a technically superior platform to almost anything else out there. True developers tend to gravitate towards what is the best. To see where .NET is heading you really need to look at Xamarin.

You act like you are the only one to have made those original predictions (re: IE declining market share, and iPhone being a big shake up to the status quo of the time). You weren't. Nobody else apart from you seems to be acting so blasé about predicting the death of .NET. To the contrary, most are thinking on the opposite end of the spectrum. F# is gaining a large amount of traction now (just look at its advance on the TIOBE index). As is Xamarin. As is Azure.

Java is dying a slow death at the hands of Oracle. None of the recent "improvements" to its core language were done correctly . Just look at their type erasure of generics. And their bastardised implementation of lambda expressions. .NET will serve as a natural destination for all those increasingly alienated developers and companies using the Java stack.
