It's not really telling on oneself. Like you said, the easy stuff (e.g. basic business process automation i.e. constructing simple database queries) happens to be economically high ROI right now. Something like 3d graphics or signal processing or whatever are comparatively niche and less likely to pay as well. Most jobs that people will actually pay for are actually pretty mindless. Even for the more "advanced" jobs, it's likely the domain knowledge and not the programming per se that's difficult.
