Respectfully, what planet is the author from? Artists, and art students, are often the most vicious pit of vipers imaginable. On the flip side, there can be a lot of ego wrapped up in engineering and coding as well, but at least the field in general tends toward a more practical approach.

As someone with a foot in both worlds, I'd say it's infinitely easier to collaborate with someone on a programming project than an artistic one, because it's easier to set ego aside when you're just trying to build a good tool instead of express something deeply personal.
