Other countries will use AI for weapons - shouldn’t the EU and US also do that to remain competitive?
It's not exactly unheard of for certain weapons to be declared off-limits by most countries even if the "bad guys" are using them - think chemical and biological agents, landmines, cluster munitions, blinding weapons and so on. I doubt there will ever be treaties completely banning any use of AI in warfare but there might be bans on specific applications, particularly using it to make fully autonomous weapons which select and dispatch targets with no human in the loop, for similar reasons to why landmines are mostly banned.
