There are two questions which can be asked for both. The first one is "can these tech can achieve their goals?" which is what you seem debating. The other question is "is a successful outcome of these tech desirable at all?". One is making us pollute space faster than ever, as if we did not fuck the rest enough. They other will make a few very rich people even richer and probably everyone else poorer.

Interesting that people call this "progress" :)
