In that hypothetical 3-years world, should we be _less_ worried about aggressive behavior by agentic AI systems acting against the intentions of their developers? I don't follow how your scenario is supposed to be an argument against worrying about alignment.
e: I do actually get how worrying about emissions or child safety or concentration of wealth might be competitive with worrying about alignment. I don't see how you have the worry "AI is very close to being able to power autonomous drones that could kill us all" and then see control of those drones as a non-problem.
Yes, we should be less worried about "alignment" of AI with the person operating the AI, and much more worried about various flavors of cheap, unmanned systems with really rudimentary (non-frontier) AI. The two compete directly with each other for attention.
