AI vs. Computational Neuroscience

avant-garde

I'm thinking about taking either one of these.
What's your opinion on both of them, and which one will have a greater impact on the world? I know that's a vague question, but I'll explain:

AI is rife with false-starts and disillusionments along the way. I guess neuroscience might be "safer" in the development aspect since you're trying to copy almost exactly what you observe. But please correct me if I'm wrong.

Also, does computational neuroscience require rigorous programming ability?
Thanks.
