Yeah, I can see the value of genuine original art going up - people want things that are authentic. And in a way, I see it like music - should people really be getting ultra rich and living off the work they did one afternoon? Or should they be paid for when they actually work and do a concert / performance? I know it's a long-tail, and the few who make it big suck up all the money, but people still want to see good local musicians even though we live in a world with Spotify. Art will be the same, people will pay for the real thing, and real artists can produce that, copiers can't.
And yes, you can often spot the AI art because people are not selective enough to filter out the ones with weird anomalies that are the giveaways. If you are selective and work at the prompts the results can be outstanding, and sometimes the "happy accidents" (Bob Ross, right?) are what make things better.
Ultimately, it is just another tool to use and future artists may be the ones who master the new tools better.
Software development also has the same challenges - many feel threatened with ChatGPT (that can write code) but unlike art the viewer doesn't really know if it makes sense or is full of nonsense anomalies (sometimes it is). You still need expertise, and it isn't writing the entire app or integration or talking to the business to extract what they really need (which rarely matches what they ask for). The people who copy-and-paste code off StackOverflow will still be the same clueless people creating crap when they use ChatGPT if they use it as a shortcut and not a tool to learn with.
