I've thought that we should be able to move so fast with software, and sometimes I see that successfully, but usually it seems like we leverage computers' superior performance poorly. To pick on frontend, it's trivial to create the next shiny Javascript framework, but what of it? Or, how come refactoring can be so painful, when the semantic change might be small? I think the flexibility and performance of computers is such that we programmers are usually incapable of effectively using them. It's like a 3D optimization problem visualization, looking for the highest peak around, except the cursor moves a lot faster than it can peruse the landscape. It zooms around aimlessly, easily getting to arbitrary places but without the capacity to make sense of them. When the train is in motion, switching tracks is hard, even if that would be the best move.
