Yea, AI has been around for a long time. Computer viruses are actually a form of AI. They replicate and even defend themselves. At this point, tho, we are past the point of no return. We can't put this genie back in the bottle. I've already been messing about with it(Off and on for some years actually) and have been able to duplicate voices, call people and the person thinks the bot is that person.
Imagine the uses(misuses mostly) this could have. Your bank calls, it sounds like your mortgage broker, but it's not. It gleans all sorts of info from you and steals your house, drains your bank accounts, name it. Politics is going to get very dirty because of this, even worse than it is now. 24/7 insanity is coming(is here).
