My personal area of interest is to work out a framework which could map human 'ideas' to AI goals, so that we may be able to monitor friendliness.

It is a lot more complex than I understand, so I I believe the best long term benefit would be for me to acquire maths skills and knowledge.

So, I have been taking a fairly intensive load of online courses to learn maths and other AI topics, to acquire as much practical knowledge as possible. I don't think it will cover all the gaps in a formal maths eduction, but being a motivated self learner I am interested in seeing how close I can get.
