That's exactly the wrong way to think about it IMO. My vision of Machine Programming is that it's a fluid OS/UI that adapts application architecture to how people actually use them. So for example you have "Deep Excel" which is trained first to give the basic functionality of a spreadsheet, but as each person uses it, it gets data about most used/combined UI elements, follow on actions etc... that "rewire" through RL the UX to behave in the way that the user indicates it wants to behave.

So each instance of the program running would be unique to each user and constantly changing to make it more adaptive to their needs. Network these in a deeper system and you can iterate on design and functionality of products way faster.
