Free of defects is the least of the problems. Doing what a customer wants is the major one. One could argue that customers will be able to write their code alone but they'll always have something else to do and will pay somebody to do it, exactly as for all the other parts of their business. On the other side maybe one wouldn't have to know one of the current programming languages, much like we don't have to know machine code nowadays. English and a good dose of perseverance could be enough.
