You lump "gun control" and "nuclear weapons" together here but those are already two wildly different things. Nobody is doing US-style-gun-access for nuclear weapons. It's not "only good guys have nukes" but everyone seems to prefer "only certain governments have nukes" to "both good guys and bad guys have nukes."
Training an AI model is easier to do with off the shelf supplies than building a nuke, but it's not necessarily true that some of the worst dystopian results of AI people are afraid of are equally likely to arise from random smaller private interests vs giant corporations or government. An AI directly plugged into the systems that control the nukes is far scarier than an equally powerful model on your home computer.
(I think this particular pause talk is largely silly, though.)
