I still just cannot wrap my mind around how we could get people there, and then all this time later have lost that ability. What happened?
"Lost the ability" is an odd way of putting it. "Lost the budget" is better. Ideally we wouldn't have to pick and choose, but since I wasn't US Dictator during the 90s, the Hubble Space Telescope + a lot of probes throughout the solar system was probably more impactful for overall scientific discovery than the counterfactual where NASA invested in continued moon landings.

Part of it is cost: In the mid sixties, NASA was about five percent of the federal budget. Another part is safety: Apollo was extremely dangerous. There were a lot of single points of failure, three astronauts died on the ground, three more were very very narrowly saved over the course of only about ten missions. One of the reasons the program was cut short was the political worry after Apollo 13 of having astronauts…
The other side to this is we don't build rockets today like we did in the sixties. Yes, some technical know-how here and there was technically "lost"--I've been in North Hollywood scrounging around for old NASA parts so that measurements could be taken and worked backwards from.
But even if we had that know-how, we wouldn't do it the same again. From novel materials to simulations to communications and onboard computing, modern spacecraft deserved to be redesigned. (For the counterfactuals, see ULA and Arianespace.)
So until someone (SpaceX) started eating that node-transition cost, we entered a period of apparent stasis. But that vacuum was energetic, and it wasn't about rediscovering lost knowledge, but inventing new kit.

We did lose the capability. Read up on the engineering behind Saturn-V. There are books that go into extensive detail. A lot of the things described there required completely novel approaches that would be very difficult to replicate in deindustrialized United States of 2024. Not to mention that cost of all this would be absolutely astronomical, far more so than it was back then.
Give me one example.

Inflation adjusted, the Saturn V was a $45bn project [1]. That's a mulitiple of the total capital SpaceX has raised (or been granted).

The best minds of our generation are working on byzantine financial derivatives, making social media more addictive, and turning fake pictures/videos/bots as realistic as possible.

It's largely a matter of incentive. In the sixties, the US had an incentive to prove that it had more advanced technology than the USSR. Once we proved we could land on the moon, the novelty quickly wore off for the public, which influenced Congress's decision to cut funding for the Apollo program. We also haven't returned to the moon yet because of cost, I would imagine.
The public was actually never in favor of the Apollo program except for when we actually landed on the moon. The government was just willing to ignore public sentiment for some reason. And I'm very glad they did.
Wow, I wasn't aware that the "only point at which the opinion surveys demonstrate that more than 50 percent of the public believed Apollo was worth its expense came in 1969 at the time of the Apollo 11 lunar landing" [1].

#37Huge congratulations to IM. Landing on the Moon is extremely difficult, despite what playing KSP will condition you to think. For them to successfully land on the Moon is a huge milestone. Now to get people back there... maybe someday.

In comparison, these landers have to do everything autonomously, the computer has to figure out where it's safe to touch down, it has to be able to figure out if a sensor is malfunctioning and if so, which is the one that's wrong.
Similarly, previous uncrewed landers were not expected to be that smart, they just aimed for a patch of land believed to be flat and hoped for the best.

Ten years ago, maybe. Today, I'm not sure. It's been a long time since I had that "wow, everyone here is ten times smarter than me" feeling at one of the big tech firms.
And to the extent the system works, it's correcting. We're seeing layoffs on one side. And moon landings on another.
