I think the argument is "a bit too nice," it isn't a binary, motivations are complicated and sometimes both feelings coexist.

If I reflect for a moment about why I personally got into tech, I can find at least a few different reasons:

- because I like solving problems. It's sad that the specific types of problems I used to do are gone, but it's exciting that there are new ones.

- because I like using my skills to help other people. It's sad that one specific way I could do that is now less effective, but it's exciting that I can use my knowledge in new ways.

- because I like doing something where I can personally make a difference. Again, it cuts both ways.

I'm sure most people would cite similar examples.
