It might add some small amount of coders to the workforce who would otherwise have never tried it out. But, that is probably insignificant. What I'm more interested in is priming people to "get" tech.
Working at small non-tech companies for the past ~5 years really opened my eyes to how completely unready for tech most people are. Old, young, it doesn't matter -- so many people have no comprehension of what developers do beyond maybe "magic", and practically shut down when asked to participate.
We don't need America to have more developers, but we do need America to get ready for a world where every company is a tech company.
