programming productivity gets absolutely massive investment -- all of secret, proprietary, and open source. They reason it seems otherwise is that software has infinite appetite for increased productivity, since there is minimal friction and energy cost commonly seen in almost every other endeavor. There are essentially two throttles on the exponential improvement in computing: (1) the speed of electromagnetic objects, and (2) the speed of humans to learn new things recently invented and use them to invent newer things.
