To me there are two distinct species of AI.
The first species is unweaponised AI, which will be data mining every second of every day and algorithms will sort this data and use it to sell you something or persuade you of something. You will be digitally pigeonholed and targeted by various entities, based on what the data says about you when sorted in various ways. CAVEAT EMPTOR!
The second species of AI - weaponised AI, will be loaded with algorithms that will dictate whether it shoots you or not.
I know which one scares me the most.
