Well, probably nothing we build will. And probably nothing we say will last forever, actually last forever. We still use the word forever and other unprecise terms in common language. I also hate it at times, how unprecise (and wrong) normal language is. But I have given up on the habit of getting mad about it and rather go with the intent and not about the single words. So no one meant literally indefinite energy here, it was meant, "potentially way more energy, than we currently need". And this is correct.
