I think the latter. For what it's worth, the 'arms' that are still protected by the 2nd Amendment are still approximately the same as in 1787 (line of sight, bang bang), as you're legally restricted from owning guided bombs, cruise missiles, nuclear weapons, etc, but even aside from that, you're practically restricted because of limited availability and/or extreme cost.

On the flip side, the hardware for Slaughterbots is basically here: TinyWhoops cost ~$100, say ~$100 to upgrade the ARM processor to one that can process realtime video, ~$100 for a shaped charge. So the hardware is super cheap, and once developed, the software to tie it all together has nearly no incremental cost. Once it's out there, that's the genie leaving the bottle.
