If I could relearn mathematics starting from elementary school, I'd get my hands on the AOPS books (Art of Problem Solving) and go through them on my own. They inspired my daughter sufficiently to pursue a math major in college.
Instead of competing with the fresh grads, he should use his age to his advantage. Learn COBOL, and he'll be in-demand by US big banks/financial/insurance companies for the next 100 years.
I generally agree with this sentiment, though COBOL may be overkill. Anything stable and not latest/greatest probably helps a lot - Java, C#, and of course C/C++. Big boring companies seem to have older people - my company's average age is probably in the mid 40s.
This is how American higher education gets hallowed out by opportunistic administrators that have carved out high-paying jobs in the non-profit sector.
Likely, this allows both SA and China to reduce their dollar reserve assets, especially since the dollar has been weaponized against Russia and Afghanistan in recent days.

Colab is a cheap (free) way to start, though you won't be training very large models for very long (which you shouldn't be doing if you are a beginner). You learn a different set of skills when you put together your own rig and install/maintain the libraries, which is something I recommend everyone to try just go gain an appreciation of devops skills. But that's not a necessary diversion for a beginner (and may needlessly increase the learning curve).
