If a classroom of 14 year olds are making a game in their computer science class, and they use AI to make placeholder images... Was a real artist harmed?
The teacher certainly cant afford to pay artists to provide content for all the students games, and most students can't afford to hire an artist either.. they perhaps can't even legally do it, if the artist requires a contract... they are underage in most countries to sign a contract.
This technology gives the kids a lot more freedom than a pre-packaged asset library, and can encourage more engagement with the course content, leading to more people interested in creative-employing pursuits.
So, I think this technology can create a new generation of creative individuals, and statements about the blanket harm need to be qualified.
