Other astronauts could be born on my space station. Generations could be populated there watching this poor astronaut never fall in.

Right. They do fall in eventually. Now that's because they have some mass of their own.

So they're not a perfectly light particle. And so they deform the event horizon a little bit. You will actually see the event horizon bobble and absorb. The astronaut. So in some finite time, the astronaut will actually fall in.

Eventually you'll fall in. Any perturbation will only go one way. It's unstable in one direction, in one direction only. But it's really important to remember that from the point of view of the astronaut, not much time has passed at all. You just sail right across as far as you're concerned and nothing dramatic happens or you might not even realize you've come to the event horizon.

You might not even realize you've crossed the event horizon because there's nothing there. This is an empty region of spacetime. There's no marker to tell you you've reached this very dangerous point of no return. You can fire your rockets like hell when you're on the outside and maybe even escape. But once you get to that point, there's no amount of energy.

All the energy in the universe will not save you from this demise.

Yeah, that might surprise people. The bigger it is, the less noticeable it is that you've crossed the event horizon. One way to think about it is curvature is less noticeable the bigger it is. So if I'm standing on a basketball, I'm very aware I'm balancing on a curved surface. My two feet are in different locations and I really notice.
