The same happened with accountants and spreadsheet software, the number of accounting jobs grew. The actual work they performed became different. I think a similar thing is likely to happen in the software world.
Almost every small business I know has an accountant or book keeper position which is just someone who had no formal education and the role is just managing QuickBooks. I don't think the need for formally educated accountants who can handle large corporate books decreased significantly, but I don't have any numbers to back that up. Just making the comparison to say I don't think the hard / cool stuff that a lot of software developers love doing is going away. But these are just my thoughts.
