That and nukes. It is ok to not want these things, but to survive as a nation state, these things will become necessary developments in order to survive. If GP is correct about some of the capabilities we're likely to see, then any nation state without these will need to begin development in order to ensure survival. Is that an arms race waiting to happen? Yes. Is there a better way? No. The alternative to an escalating arms race is actual war.
We will never be done with power hungry ideologues, we will never be done with Communists whose sole mission is dominion over the whole world, we will never be done with petty despots (looking at you, Putin) who so wish they could play a meaningful role on the world stage. All of these have every reason to develop a new super weapon to tilt the balance of power in their favor.
Iran, for example, has started its centrifuges again. They also have some new ones that spin at 10x the speed of their old ones. They are very close to possessing a nuclear bomb. Up until the end of the Trump presidency they had halted production of uranium and talks were going well. Biden has about the weakest foreign policy of any president in the last half century.
Part of that effective foreign policy is the military might the US has. (Why do we have 5 carrier battle groups? Why does Britain only have one? Why does Russia have a single carrier that's in rather poor repair?)
If killer drones are an effective war-fighting tool (an it appears they are), they are inevitable. What we need to ensure is that they are used as humanely as possible.
