It's a dumb/lazy/specious talking point. You can kill someone with a pencil just like you can kill someone with a gun, but the gun scales up the danger so we treat it and regulate it differently. You can kill someone with a bike, a car, or an airplane, but the risks go up at each step so we treat and regulate the respective drivers differently.

If AI gives every individual the power to suddenly scale up the bullshit they can cause by 3+ orders of magnitude, that is a qualitatively different world that needs new considerations.
