While I also disagree that we should ignore tractability for the purpose you indicate, the main point here is more “if we’d chose the ozone layer as an analogy we are suggesting the problem is trivially easy” which doesn’t really help with solving the problem and it already seems extremely likely that AI risk is much trickier than ozone layer depletion.
I think we’re talking past each other.
