Just yesterday I published a very long post about the economics of open source. As part of that argument, I mentioned that the cost of writing software has collapsed, and that meant the variables in the equation had changed for the first time in thirty years. That led me off on a tangent that grew into this equally long post. I had a bunch of questions to answer. Has the cost of creating software really collapsed? Can I prove that? If the cost of actually producing code goes to zero, what parts of the job of “software developer” really remain?...
