I see it very similar to 20th century space tech. Yes, they are technically providing something unthinkable otherwise. But what is their real utility? Most if not all the biggest civil utilities like remote sensing, radio communication and navigation are quite well doable also without them. They fail to deliver the biggest dream of trans-galactic travel and there is no even roadmap to it. It does not help much our everyday ground-based transportation. So in this century we start to think: maybe this is just big waste of energy, which now will need to be spent to resolve way bigger real issues. Like to keep our current planet inhabitable.
