An AI bot operated by Wells Fargo just slapped sell ratings on Google and Facebook

Google, which makes almost all of its money on ads and internet user data, is undertaking herculean efforts to get a grip on artificial intelligence (AI). It's trying to develop software that allows machines to think and learn like humans. This includes the $525 million acquisition in 2014 of DeepMind, which is said to have lost an additional $162 million in 2016. Google is trying to load smartphones with AI and come up with AI smart speakers and other gadgets, and ultimately AI systems that control self-driving cars. Facebook, which also makes most of its money on ads and user data, is on a similar trajectory, but spreading into other directions, including a "creepy" run-in with two of its bots that were supposed to negotiate with each other but ended up drifting off human language and invented their own language that humans couldn't understand.
