You don't have to retrain an AI to spin up another instance - just download a 4gb weight file via a magnet link floating around the internet and run some python code in terminal on your old PC. This kills the comparison.

And training a real living breathing person in a rich OECD country is going to be costly - no offense meant, I'm actually not from OECD.

You can create a lot more copies of the AI.

But then again, when it comes to commercial needs, a human doesn't need "retraining" every time you ask them to draw something they weren't familiar with when they went through art school...
