Within 10 years chances are just about everything will be IP encapsulated, over this or that phy :-). POTS may well be still around, but not because they are not a dying technology - which they of course are - but just because the infrastructure they have is so large it will take longer until they die out. It is still nice to have them, though - the phone application here is nearly 100% to call the electricity company when there is a blackout and the ISP when their service dies.[Remarkably stable this ISP is, though, sometimes the net works for months without a hiccup, since recently delivering 1 MbPS (down) at around $12/month.... OK, plus the typically unnecessary cable TV which also costs as much and got a bit more useful recently - the English premier league matches are on again :-)].
