It seems there is still some hope to see Croquet (or, OpenCobalt which took off from where Croquet stopped) alive and based on latest Squeak and more importantly using Cog VM. Matthew Fulmer reports it here. The potentials are magical as explained by Howard Stearns.
I am probably too selective, anyway my models for computer science/software engineering (one of them would disagree on both definitions) are just two: Donald E. Knuth and Alan Kay. The first one continues to surprise me with the depth, clarity and joy of his works: from TeX (well, I use LaTex but it does not exist without TeX) to The Art of Computer Programming to Literate Programming. About the latter, I was one of the blessed to be present to his Turing Award Lecture: he shocked me to the point I had two sleepless nights so angry I was about having wasted so much time in useless (computer) matters!
