If anything, the rate at which capable software professionals can create value has dramatically increased over time. Software is not a zero sum game, cumulative advances make it possible to solve an expanding frontier of problems with increasingly effective and efficient solutions.
Creation of knowledge products both facilitates the further production of new knowledge products and expands the scope of new knowledge products which can be created. This process is like a chain reaction where the potential energy unleashed may ultimately exceed any practical scale modern economics has meaningfully considered.
Software costs almost nothing to deploy, even on a global scale, versus its potential value delivered; and it can be created or improved with almost no additional consumption of resources vs (the programmer) simply existing.
