Yes - this will make artists hyper productive IMO; and will make a lot more people willing to make art! If you've ever had a little ditty and wondered what it would sound like as a violin concerto in D minor, now you can know! If you ever wanted your wife painted as a Rembrandt, there you have it. If your five year old comes up with an idea for a fun video game called Laser Chicken, now his friends can play it.
Imagine pairing this with bespoke automated clothing output - take a photo of an outfit, verbally describe the changes you want to it ("a little more debonair, dark lapels, 1920's styling"), click a button, preview it as it would look on you in several recent pictures you took, and a week later your tailored suit arrives. Now for sneakers. Hats. Bags. Watches.
The 20th century was about mass production to ensure everyone could have things: food, clothing, transport, entertainment. The 21st century may turn to expression: allowing each person to express themselves however they want in their goods and services. Or just following along to buy whatever your favorite tastemakers recommend. However involved you want to be!
The world is about to get a lot weirder and more interesting.
