If you want to earn money, create the most revenue. The problem that most technical people seem to have is that they think a qualification is a licence to print money. It isn't. The majority of people who obtain qualifications have no idea how to make money (that is why they are doing the qualification rather than making money, and this effect increases with the complexity of the course of study). So if you want to make money and your interest is AI, sure do a PhD...but at some point, you are going to have to work out how you can use those skills to sell something. I think, at some point, there is going to be a rude awakening. Right now, we this situation where you can tap up some VC idiot to pay your salary for a few years whilst you fuck about on some bullshit. You can get acquired by some megacorp with a ton of cash and have no accountability from shareholders while you light huge stacks of their cash on fire...this always ends. Always. You are either a bureaucrat chasing qualifications to get no-accountability jobs or you are someone that can create value for other people. I am not knocking any kind of advanced degree (I have one). But the point of it is not money. So even posing the question is totally misguided.
