Even if you are completely closed of from AI as a profession, there are still way more possibilities, even in the same general field(computer science).

Even then you could go through a career change. He looks like hes in his 20s or 30s which isnt late at all.

I would refrain from saying he took his life while worried about his career.

He most likely wasn’t in a good mental state and needed support from his friends and family. Healthy people can tolerate a lot more than career death.
