Some people think AI is the best thing since sliced bread and mankind is about to make a giant leap. Some people think the end of the world is nigh. And some people think that AI is just a powerful autocomplete.
I'm more on the side that AI is a powerful autocomplete. I don't think we understand sentience and I don't think the current AI will lead to it. You train AI like you train a dog. When you give a positive response, the AI will do more things like it just did.
I do think that it could be dangerous, but not because AI would take over the world. The danger is that people could think AI is all-knowing and blindly follow what it says.
