The problem with this reasonning is that it relies on potential, on hypothetical, on hope. But the problem is not, it's just physics, and it's comming for sure

The problem with this reasonning is that it relies on potential, on hypothetical, on hope. But the problem is not, it's just physics, and it's comming for sure. Not attempting to solve it with what we know right now because we might pull off something out of our sleeve at some point doesn't seem neither rational nor scientific to me. However, if we do tackle the problem, we give ourself a margin of security that we can later on remove if we actually manage to innovate out of out petri dish.
