"a talented recruit can expect"
This is like being the first or second round draft pick in the NFL/NBA.
Not your typical person.
Yeah, they surely want folks with advanced degrees from universities with the top AI programs or their leading industry competitors. If you just dabble with AI at home and take a free online course, don't even expect to hear back from them after submitting your resume'.
It reminds me of the kinds of Wall St. jobs I heard about, 10-15 years ago. If you had a double major in CS and finance, from a top university, you could land a job at a hedge fund and make $350k. The average developer need not apply.
Better question is where can someone get the training to get into this field of IT.
It's not hard to find online classes. They'll give you a basic grounding in the theoretical underpinnings, plus teach you the main points about how to apply AI to tackle different sorts of problems. That might get your foot in the door, at most places offering more normal salaries - especially if you have some adjacent work experience to draw from.
I took Andrew Ng's original Machine Learning course, at Coursera, not long after it launched. It was derived directly from his Stanford course, but they watered down the math and (I think) did a bit more hand-holding through the exercises. I'm not sure which of their current courses it is, but perhaps they split it into multiple ones:
For me, the time commitment of those courses was the biggest problem. I don't know if it's the same as before, but it's no joke. You'd think online learning means you get to go at your own pace, but they kept it to a normal university class calendar + 1 week grace period.
