The optimistic spin is, I think, software developer as a career dies, just like sysadmin. But just like dev-ops, a new to-be-named role (or set of roles) will arise

Web front-end and backend developer as a career dies, probably desktop/mobile application development too. However, some of the more specialized software developer roles are likely to survive; none of the people on the Linux kernel team have anything to worry about and the same goes for the GCC folks.
