Suggestions for getting retiree / second career folks interested in AI Safety?

I know someone who recently retired and is interested in taking on an intellectually engaging part-time project. He is quite gifted both analytically and in terms of people skills and business acumen.  (He has the horsepower to do quantitative work, having pursued a PhD in Electrical Engineering many years ago, but is probably pretty rusty, as his career did not require intensive mathematical work or computer science for the last 20-30 years.)

I think he would find it interesting and worthwhile to contribute to AI safety work, but I'm looking for things I can share with him to:

1. Pique/assess his interest in the field. (I would say he's somewhat curious, but not at all actively bought into the importance of AI safety as a place for him to devote his time and energy).
2. Provide opportunities for him to get involved.

Any suggestions? A friend suggested:

I'd recommend reading some blog posts on 80k/alignment forum/less wrong to test interest and then taking the bluedot impact AI safety fundamentals course

https://80000hours.org/problem-profiles/artificial-intelligence/ is probably the best starting place if he's not yet convinced that it's an important problem to work on.
