Even the most excellent education system takes several yeas to educate a high-schooler to a level of a junior engineer. Then several more years are needed for the best of them to become senior engineers, with the knowledge and experience that a university alone cannot provide.
So, we're looking at a decade-long project at least, even if everything goes as planned, and crazy fast, in the technical and administrative departments.
All the more reason to start now I guess. Putting it off isn't going to get them that knowledge and experience any sooner. If something happens over the next 10 years that eliminates our need for memory chips things will probably be either too messed up or too wonderful for anyone to cry over the years they needlessly spent trying to secure a domestic source of RAM.
