Ask HN: Is there an AI knowledge path?

I'd start by clarifying what you mean by "an understanding on AI" what do you mean by AI? Do you mean machine learning as a scientific discipline? or something else. You can probably start with Wikipedia to get a map at that level.

I often see https://www.fast.ai/ recommended as an answer to this question, but I have not used their courses so I can't comment on their utility.

You could get a map of current industrial capabilities by looking at the white papers and documentation for the AI web services offered by Google, AWS, Azure.

Two podcasts with interviews with researchers and developers: MLST, Latent Space

I started with this and gained a lot of insight, though it's definitely very high level: https://learning.edx.org/course/course-v1:HarvardX+CS50AI+1T...

Start with Karpathy's videos on YouTube. He has some real talent for teaching.

It's good to have strong math foundations for the AI career.
