We put men on the moon with pencil and paper.

Trillions and trillions of dollars of technology later, and the best we can do now is fly by and wave.

Jesus, it has absolutely nothing to do with not having the technological capacity to go back and land on the moon, and everything to do with political and social will. We have rockets doing gymnastics in the sky and landing doing back-flips, you really think we've regressed because "we're not doing pen and paper"?
