smalltalk is so dead nowadays that I see no point wishing to move out of it's shadow. A lot of research has been done from it, many different languages have proven to be more interesting from many aspects etc etc no need to argue about that.

The good thing about bring it back to life is for educational purpose, as, unlike many other research, smalltalks tended to have more complete and mature development environment, and I believe it might be inspiring get a feel of how to do things that way, I doubt any kid today will be inspired by doing something on vxworks
