AI scares me. Even though I've used neutral networks and even more complex models/networks in projects and have a fair understanding of how they work, they still scare me a lot. Even though we are far away (supposedly) from creating a sentient AI, I can't help but think that AI will turn into something like "I am Mother" rather than C-3PO.

And yes, I understand that AI and machine learning can help us in ways that will advance our abilities in medicine, science, etc but we're human. if something can be used for evil, we should be sure that that will be attempted. We, as a species, have an annoying need of being the first and having control of everything. Only that AI may, in the future, be uncontrollable.
