Sounds to me like someone who enjoys programming as an intellectual pursuit, as a craft, as an art. I suspect there are more than a few students in the CS program that also feel that way. Clearly they're the intended recipient.

If programming is all about making the most money then by all means disregard everything he says.

I think it is fine advice for someone doing computer science in academics. It is just bad advice for students going into industry.

It can be both. People ride horses for leisure; no one commutes on them.
