Hopefully we don't end up relying on them for anything serious!

All jokes aside, there is also the diluting factor to take into account. A lot of the mechanical/boring/repetitive software engineering type tasks (e.g. javascript/php/java code monkeys that spend half of their working hours looking up answers at stackoverflow.com and the other half trying to implement said answers by clumsily glueing together 3rd party code) can be expected to go away by automation in the not-too-distant future.

Thus we end up with extreme dilution of the prime domain by substandard/incompetent coders.
