Unfortunately Étoilé seems to have been inactive for a decade, and even Apple seems to be abandoning its Xerox PARC influences as the old guard retires and passes away (RIP Steve Jobs, Larry Tesler, and Bill Atkinson). Ever since Apple struck gold with the iPhone and derivative platforms, Apple hasn’t been the same.
I’d like to see the ideas of Smalltalk and Lisp machines revisited for the modern era as a model for workstation-class personal computing. Smalltalk and Lisp environments pride themselves on flexibility and malleability (though it’s understandable to rethink some of these things in an era where security is very important), while mainstream personal computing these days feel less like productivity boosters (remember “the bicycle for the mind”) and more like advertising platforms and anti-competitive, rent-seeking moats.
