You're right, it might just take one creepy scientist or engineer to cook up something incredibly evil and then put the whole world at war. Imagine have that type of tech that can do mass damage.
I agree that war robots will come first, afterall, they're expendable and far less valuable than human lives.

Personally many people will prefer to have robots friends lol, I think they're probably make better helpmates and conversational partners, unfortunately I think that's too sophisticated tech to exist in 2025.

How has it been with you?
