Note: Squeak/Smalltalk were revolutionary at the time and influenced many of the modern languages we use today. The way forward isn't to use Squeak/Smalltalk (which Alan also wanted to kill off), it's to be inspired by their ideas, embrace the good, rework the bad and to build something better.
Yes. Smalltalk was a work of genius. It seems like every good idea in modern languages I learn about turns out to have been poached from either Smalltalk or Lisp.
