This all seems straightforwardly correct, so I’ve changed the line in question accordingly. Thanks for the correction :)
One caveat: technical work to address #8 currently involves either preventing AGIs from being misaligned in ways that lead them to make threats, or preventing AGIs from being aligned in ways which make them susceptible to threats. The former seems to qualify as an aspect of the “alignment problem”, the latter not so much. I should have used the former as an example in my original reply to you, rather than using the latter.
