I think it's only a matter of time until this becomes reality. It's almost inevitable.

My prediction last year was already that in the distant future - more than 10 years into the future - operating systems will create software on the fly. It will be a basic function of computers. However, there might remain a need for stable, deterministic software, the two human-machine interaction models can live together. There will be a need for software that does exactly what one wants in a dumb way and there will be a need for software that does complex things on the fly in an overall less reliable ad hoc way.
