It can only do that based on what's been fed into it, and it's cheap because artists aren't paid at all. If there was even a small amount per licence, these machines would quickly have a cost. IMO we don't need the machines gone - they're just a low-end version, with proceeds still going to artists.

The only reason the engines are low cost is because 1) they're absorbing costs, 2) they're not paying creators anything. If machine outputs were (say) half the price of paying a creative, but creatives were getting some of that money, would that be so bad?
