Quick Thoughts on New Career Profiles on 80,000 Hours

I recently received a newsletter from 80,000 Hours noting that new career profile pages had been posted on the 80,000 Hours site. Since I’ve explored a couple of the careers mentioned there, I wanted to share some thoughts and ask some questions:

Data Science:

The career profile mentions that Zipfian Academy is a high-quality bootcamp which accepts people who don’t have a science PhD. I know that lots of people from LW and EA have gone through App Academy’s program and have recommended it; has anyone here attended Zipfian Academy?
Has anyone gone to one of the other data science bootcamps?

Actuarial Science:

I’m going to play devil’s advocate here, rather than being balanced; I think that becoming an actuary could be a great choice for some effective altruists. Still, there are a few issues that weren’t explicitly covered in the 80,000 Hours post on actuaries:

Lots of the work that entry-level actuaries do could be automated in the future. Re-computing insurance rates for a given policy in a given state is sometimes just an issue of plugging new numbers into an old excel spreadsheet.
I’ve read a couple posts on actuarial forms complaining that there is a surplus of trainee actuary candidates. Posters sometimes complain that this is because of e.g. recent news articles which have (correctly) claimed that actuaries have high job satisfaction and high salaries.
Actuaries typically spend about a fourth of their first 4-8 years of work obtaining a professional certification. If the field becomes deregulated, salaries for upper-level actuaries could drop substantially.
