Huh? The research done to develop the flight control computer for Apollo (and IBCMs of the time) lead directly to modern microcomputers. It’s hard to name something more impactful than that.

It could easily have taken another decade or two to develop the modern computer if not for the resources spent in the space program at that time. It still would have happened, but Apollo and the space program was soaking up something like 90% of computer demand for a full decade. Computers went from room sized behemoths to the size of a file cabinet in that time.

Im not sure that's an honest rhetoric, we have seen many other things in the last few years that have increased the demand for compute. It would seem lunacy to propose, to accelerate the miniaturization of compute we need to send a bunch of people to bounce around the moon, then we can forget about the space nonsense. If the goal was begin the path that leads humans into so many resources it would take centuries before fighting over something was more profit than going to the next empty rock, we clearly failed.
