Well, he's not wrong technically, but the context feels like it's obviously missing. We have no Saturn V vehicles anymore, nor can we build them again. Starship might require that many launches to get to TLI, but with reusability, it probably can. Not to mention that the cost will come down a bit. So it can at least do it soon.
I'm sure others have more coherent and thought out rebuttals.
why can't we build them again? were the blueprints and knowledge lost? deliberately destroyed? genuine question
Because it is based on obsolete technology. You wouldn't want to build a flight computer with hard-wired (as in literal wires) software, would you? A lot of it would also have to be reverse engineered, to the point where you might as well build a new vehicle.
We can use an FPGA for that
The software was the thing that was in the wires, not I/O.
The wires would be replaced by FLASH memory.
Wouldn't they use a MROM or something instead, because flash memory can be quite volatile in the extreme conditions?
