The cells concept seems like a global git repo atop a NFS. While such a thing might help the people who choose to use it. I think you will have to be very careful to avoid the competing standards trap. https://xkcd.com/927/

If you are truly passionate about bringing programming to more people, then I suggest starting by trying to teach each existing language to a different person who doesn't know programming. The intro experiences of each of those people should confirm or refine your ideas about what needs to be built in order to get the maximum number of people programming.

Alternately, you could start with the observation that it seems to be the case that even most programmers do not make most of their own solutions. If that is true then a good thing to build might be a general programming language that would get most programmers to start making most of their own solutions.

Either way, the result should be a language that is so much simpler to write in and that provides such a small time to useful solution that not only will most programmers choose to use it to solve their own problems but most programming instructors will choose to use it as a first language.
