If we have enough cheap energy, the other stuff doesn't matter. It is like someone from 200AD being worried that we're not all working the fields and we're going to starve in winter - that isn't a constraint on modern society, we broke it with cheap energy. Fuel goes in the machine, the machine does lots of work, and then we get food. In fact, it might literally be like someone in the UK in 17xx worrying about the early industrial revolution because of climate change. The cost benefit calculation favours the industrial revolution by a heavy margin. If energy gets cheap enough, climate change happens and nobody needs to care. |

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).
