IMHO we are about due for a displacing technology - e.g. speech-to-text, look-and-click - that will leapfrog many of the current concerns about OS etc etc. The word processor, software, everything will need new rules... all bets are off once the screen and keyboard are gone and we are all facing change whether we stay with the "same" OS or not.
Perhaps we should consider ourselves as switchboard operators on the eve of transistorized telephone exchanges. IMHO the best thing to do is keep earning a living and attend night school rather than believing we are safe as long as we always purchase the very latest switchboard promoted by our preferred vendor.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
