Machine Learning

I was explaining some of the stuff I work with in class to a friend who wants to be a career artist. She knows it's a hard career to make it in, but she's got talent and believes she can do it, so who am I or anyone to say she can't? Anyway, I was talking about GANs because I had an internship where we were working with them for a project. When I described what they were and what they were designed for, she started to get a bit concerned. It wasn't that she suddenly doubted her own talent, but when it comes to AI we don't know where the upper limits are (if there even are any), so in theory down the road they can present legitimate challenges to working artists. Not only would the requisite talent to work in the arts go up, but if AI gets good enough, in theory within the next few decades generated art can be genuinely good and tough to distinguish from high tier human work. I'm still a student, I don't know much about discriminators or AI detection, and it's not something I look into much in my free time. Is this a legitimate fear for artists to have? Or are there techniques which can pretty accurately identify GAN generated work most of the time?
