That's a bit strong. There is a lot of skepticism, but if anyone
can do it well enough to bother it's Dave.

I'll repeat my criteria:

At the API level, a set of abstractions that would make it remarkably easy
and fun to do GUI programming.

At the system level, some way to make it remarkable easy to make and
maintain ports to many underlying drawing and windowing systems.
