Everything I know is from the documents, papers and videos that I manage to scrap from the Internet.

My experience with Oberon, lead me to track down how Wirth learned about such systems.

Additionally, I got to learn Smalltalk in the form of VisualWorks before Java was known to the world.

So I extrapolate my experience to how it might have felt back then and find it sad we are still trying rediscover it.
