Not so — the person you're responding to was demonstrating that important things had not in fact been invented, while your example only worked out because we did actually invent stuff.

Indeed, even today electricity is only about 10% of humanity's total power usage, and that's with batteries cheap enough to make electric cars viable. (Bit of a shame that the alternative to batteries, hydrogen, still isn't cheap enough to be a great contender today, even despite the strong incentive to replace gasoline during the height of pro-nuclear attitudes and the OPEC-induced fuel crisis).
