Future of irrelevance to who exactly? The 1-in-10000 users who like to play with root level access and scripts and stuff perhaps, but do the other 9999 even notice the change? I'm thinking not.
Granted it's a big change from earlier times, the strategy of sandboxing works really well for security and general OS integrity (as iOS has proved) in a world that has no patience for fragmented and exploitative software. Perhaps we lose a little something in the process, but it's in the service of a better overall integrated service and experience.
Oh and by the way: Microsoft is going the same way too with Metro.
