No, it is not - in fact DC is even better for long distance transmission than AC ever was http://en.wikipedia.org/wiki/Direct_current http://en.wikipedia.org/wiki/Alternating_current http://en.wikipedia.org/wiki/AC_power http://en.wikipedia.org/wiki/HVDC http://en.wikipedia.org/wiki/War_of_Currents .AC won because in XIX century (and to to the second half of XX century) changing voltage of DC was hard and inefficient (but it is not the case today). But we would still need transformers, and that is easier done with AC than DC.

I believe Moore's Law (after needed change) can be applied to anything that is actively used and developed - eg. price of space launches per kg halves every ~10 years, amount of qubits doubles ~6 years

Producing products that can last decades but for which time of exponentiation is <5 years doesn't make too much sense - extreme cases are our current CPU's (heck, my brother has P4 3GHz inside his box, and my laptop has T3400 (2 core), from which 1 core has computational capability of his entire P4, while entire CPU (on 100% load) takes 4-5 times less energy than P4) were [total] computational capability is doubling every ~2 years, making it rather meaningless to produce systems that can last decades.
