Facebook has a lot of data. They can use that to train models and sell them out as services for other companies as one example. They can also use it on tracking data to help them improve their sites for the things they want to achieve. They can use it to look at your data and determine what a feed that would keep you there longer would look like. All kinds of things really.
Maybe but people who are good at things already can use it as a tool to be better. You can combine the skills you do have with ai for the skills you don’t have to make something you never could have before.
I like to make games and for me this means I could make my own game music. I just don’t have the skills to do that on my own and make it sound good. But with ai I could get music that matches the quality of my other work.
