I think you're right at the edge of explaining why this "laziness" is a good thing. Everything that we have made is built on what we had before, and abstracts away what we had before. 99% of us don't remember how to make even the simplest Assembly program, and yet we unleash billions of instructions per second on the world.

Even outside of math and computers, when was the last time you primed a well pump or filled an oil lamp? All of these tasks have been abstracted away, freeing us to focus on ever-more-specialized pursuits. Those that are useful will too be abstracted away, and for the better.
