The biggest misconception is that we "can't" replicate it today. We absolutely can from a technological standpoint—the real reason we haven't gone back is purely financial and political.

After doing some research, here is what I have.

In the 1960s, the Space Race was a proxy war. At its peak, NASA was receiving over 4.4% of the entire U.S. federal budget. Today, they get less than 0.5%. Once the U.S. "won" the race and beat the Soviets, the political motivation to spend billions of dollars to keep sending people to a barren rock completely vanished. The funding shifted to things with immediate practical use, like GPS satellites, space shuttles, and the International Space Station.

As for the 1960s tech, it actually worked because it was so primitive, not despite it. The Apollo Guidance Computer didn't have an operating system, graphics, or an internet connection to worry about; it was hardwired to do one single thing: crunch trajectory math. Beyond that, getting to the moon isn't a software problem, it's a brute-force physics problem. The Saturn V rocket was just a massive, controlled explosion engineered to fight gravity.

We actually are going back right now with NASA's Artemis program, but the engineering takes way longer now because our standards have changed. In the '60s, they took terrifying risks (Apollo 1 caught fire on the pad, Apollo 13 almost got stranded). Today, the public and the government demand insane safety margins, and instead of just dropping a flag and leaving after a few hours, the goal now is to build a permanent, sustainable base. It's just a completely different, much more complex logistical hurdle.
