I agree with you. I suppose what I should have said is that software engineering is becoming much more lateral than ever before. Though it seems like the verticalness is decreasing. Hmm, I wonder if the total "area" of "verticalness" times "lateralness" has stayed constant over time :) Perhaps it is a reflection of how much time an engineer can spend on learning things, and I would expect the "area" is different across the distribution of programmers. But maybe the average area has remained invariant.
