I agree that having many shots is helpful, but lacking them is not the core difficulty (just as having many shots to launch a rocket doesn’t help you very much if you have no idea how rockets work).
I do really feel like it would have been really extremely hard to build rockets if we had to get it right on the very first try.
I think for rockets the fact that it is so costly to experiment with stuff, explains the majority of the difficulty of rocket engineering. I agree you also have very little chance to build a successful space rocket without having a good understanding of newtonian mechanics and some aspects of relativity, but I don’t know, if I could just launch a rocket every day without bad consequences, I am pretty sure I wouldn’t really need a deep understanding of either of those, or would easily figure out the relevant bits as I kept experimenting.
The reason why rocket science relies so much on having solid theoretical models is because we have to get things right in only a few shots. I don’t think you really needed any particularly good theory to build trains for example. Just a lot of attempts and tinkering.
At a sufficiently high level of abstraction, I agree that “cost of experimenting” could be seen as the core difficulty. But at a very high level of abstraction, many other things could also be seen as the core difficulty, like “our inability to coordinate as a civilization” or “the power of intelligence” or “a lack of interpretability”, etc. Given this, John’s comment seemed like mainly rhetorical flourishing rather than a contentful claim about the structure of the difficult parts of the alignment problem.
Also, I think that “on our first try” thing isn’t a great framing, because there are always precursors (e.g. we landed a man on the moon “on our first try” but also had plenty of tries at something kinda similar). Then the question is how similar, and how relevant, the precursors are—something where I expect our differing attitudes about the value of empiricism to be the key crux.
Well you could probably build a rocket that looks like it works, anyways. Could you build one you would want to try to travel to the moon in? (Are you imagining you get to fly in these rockets? Or just launch and watch from ground? I was imagining the 2nd...)
