I was very sceptical towards the recent hypes (space exploration, cryptocurencies, self driving cars, ...) which turned out to be fads but this time ... this time I'm going to guess it isn't going to be a fad. Well it depends what we imagine by "AI" - will you have a robot pal like in movie I Robot or AI Artificial Intelligence? Probably not. Will AI predictions and learning be put into majority of programms and quite clever AI voice-assistants will appear like in movie Her? Yeah, I guess this could happen. My main reasons are:

1. It actually isn't that difficult, machine learning isn't new and very theoretically speaking, as long as you have enough computation power, nothing is stopping you. Like at the moment I can't think of any limit
2. Laws to stop it would be very difficult. You cannot just say "No AI!", I mean people can run it at home, how do you want to stop it? Which leads me to other point
3. The OpenSource community had also made progress in the area
4. Major players are heavily investing into it
