I think the problem is not the technological advancement, it’s the limits of physics which are the same as in today as it was back in 1960s.

We have immense computing power now compared to 50 years ago. But that doesn’t help to escape the gravity well of earth. We’re still using the same chemical rockets to go to space, haven’t invented any new type of rocket drives
