I agree partially, but I'm sure we've barely scratched the surface on what is possible with the knowledge that we already have and has already been proven by scientists. They might come up with novel solutions that are more or less correct that don't need extensive real world testing and be able to change the world very quickly that way. There are mathematicians who's work is entirely theoretical and haven't been applied to the real world, then suddenly a use is found for their stuff 30-50 years later.
