I have already been seeing obvious AI images showing up in Click Bait ads. (one was an ad showing a $50 bill, and I would bet a nickel it was made by FireFly.) I recognized the distorted face image created. Sometimes they can be disturbing. But I know it will improve and there are other art AI programs that are pretty good.
I think it is inevitable, it will be increasingly used in creative projects, art, photos, voice, voice-over, actors, movies, stock market predictions, weather, manufacturing, design, house cleaning, driving cars and trucks, food preparation, checkout, stocking shelves and delivery, manipulating public opinion and mind set of the masses, keeping control of the populace, policing, warfare...
Soon people will voluntarily hook their brains directly into this to be smarter, think faster, play games, augmented/virtual reality...the stuff of science fiction is upon us.
