Some TL;DR:

The article speculates that the emergence of Windows Store app platform from the Windows desktop could become similar to the emergence of Windows from DOS, and that newer technologies will similarly only be available on the Windows Store app platform.

It describes the locked-down properties of the Windows Store, and, extrapolating from the current certification requirements for Windows Store apps, it asserts that a game like Skyrim would be denied certification on Windows Store in 2032 because of its PEGI rating.

BTW, Microsoft did back down from that policy (not allowing games like Skyrim and its ilk): http://arstechnica.com/gaming/2012/10/microsoft-to-allow-mat...
