I agree that Alan Kay is brilliant, but to be completely fair, if Squeak is the way forward, I think I'm happy where I am. It's not bad, but the tradeoffs are such that it's hard to imagine ever using it for production software.
Well... you get it...
Well, it's still the language from the year 1980. The very fact that you judge a 1980-vintage system as "not bad" compared to existing alternatives is telling in itself. Alan is working on a 2010 version even as we speak. :-)
