Make a case that it's more profitable to take any of the courses you suggest and you might be on to something but they aren't. All of those things take time and time is money when you're running a business.
That’s the whole point: Companies are doing this because it’s easier and cheaper for them, and those doing it now are first-movers who don’t care about how catastrophic the end result will be for the rest of society as they’ll have their training data moat.
It should be obvious, but the things that are most profitable are not always the things that are best for society as a whole. That’s why we have regulation.
