Kinda of like Leonardo da Vinci drawing up plans for helicopters. I doubt if he ever imagined he would actually fly in one day.... but he saw the possibilities, and a few hundred years later it was realized.
Like I said earlier, I'm a big fan of Roger Penrose... I think a lot of his ideas make sense, and my personal favorite for what actually might come to pass is something along the lines of a
Penrose Mechanism using an artificial singularity. Now, obviously, this is at the Leonardo helicopter stage at present... but let it bake for a couple of hundred years, and who knows where it might lead? Maybe nowhere. Or maybe we might come up with something even more outside the box that works.
But to just shoot everything down and say it's never going to happen strikes me as moronic failure of imagination and an utter lack of appreciation for all the obstacles we have overcome in the past. We're homo sapiens. It's what we do.
