On the other hand, If we went to the moon without any real computers
in 1969, Why is it so hard to do now with 37 years of further
technology and scientific advances behind us?
It would be a lot easier to fake it than to actually do it.

Do you think all we need is fast computers to make it easy to go to the
moon?

Do you think materials have gotten that much lighter in that time? Have
rocket propellants gotten any more energetic? Has engineering and
testing advanced spacecraft become a low-cost enterprise?

Our spacecraft are still made of Earthly materials and are still
powered by rockets. They're still crewed by fragile human beings. Those
37 years of advancements haven't amounted to much when it comes to
space transportation, any more than they've transformed cars or
airliners into anything better than fancier versions of what we had in
the 60s. It would be hugely expensive merely to duplicate the Apollo
hardware. NASA hopes to do something more ambitious than that. That
will be an extremely expensive enterprise, if it ever gets done at all.
