I’m pretty confident that if loads more money and talent had been thrown at space exploration, going to the moon would be substantially cheaper and more common today. SpaceX is good evidence of this, for example.
As for fusion power, I guess I’ve got a lot less evidence for that. Perhaps I am wrong. But it seems similar to me. We could also talk about fusion power on the metric of “actually producing more energy than it takes in, sustainably” in which case my understanding is that we haven’t got there at all yet.
I feel like your qualifying statement is only true of the last one?
