AI and autonomous weapons?
The automation of warfare is more about logistics than anything else, before a tank aims and fires it needs to be on the battlefield in working condition with ammo in its magazine and fuel in its fuel-tanks. Building a tank is an effort intensive process, building many tanks is a very effort intensive process, transporting a tank halfway around the world is expensive, transporting many tanks halfway around the world is very expensive. Keeping those tanks armed, refueled and in working order is a very expensive and effort intensive task, anything that reduces the cost and effort lets you deploy more tanks, having better tanks is sometimes advantageous, having more tanks is always advantageous.
One absolutely unbeatable tank will win every battle but an endless supply of tanks will win a war and even the unbeatable tank still needs to be rearmed, refueled and repaired, without that support it's inevitably an inert mound of metal that can't do anything.
An autonomous tank is a gimmick, an autonomous factory will conquer the world.
what do you think are the most technology and consequences if unregulated
The most exploitable one, I don't see much difference between mind control, holding a gun to someone's head or making them hopelessly financially dependent on the medicine only your company produces.
