This was already shown for MLPs some years ago, and it is not really that surprising that it applies to many other architectures. Note that while learning can take place locally, it does still require an upward and downward stream of information flow, which is not supported by the neuroanatomy in all cases. So while it is an interesting avenue of research, I don't think it's anywhere near as revolutionary as this blog post makes it out to be.
