automation of software development is inevitable as there is huge financial incentive to do so. Businesses view developers as expensive middle men between them and the product -- much like the assembly line workers in a factory.
I am betting that typical crud business apps and majority of web development will be the first fields experience heavy automation, which also happen to be the areas where the vast majority of software jobs exist today. But this won't happen overnight, so lets enjoy the good times while they are rolling :)
