Well stated. A phrase that comes to mind is that "Over time, a quantitate change becomes a qualitative change."
Take Moore's law for example. The doubling of transistors/halving of their expense first allowed more efficient computation in the original manner, but now that qualitative change has started to alter the very nature of computation- omnipresent computation in all man made devices doesn't mean our spreadsheets run faster, but rather humanity exchanges information and communicates in an entirely different manner than it did a generation ago.
Likewise, I believe we'll see the gradual automation of 'useless' jobs change from an event we can work around by retraining or switching careers to an obsolescence of the vast majority of human labor. There are some nagging statistics about unemployed engineers that I believe back my assumption, especially considering that engineering positions should be the new careers people retrain to.
