Outside the issue of OOP, Alan Kay has always been an icon to me, since I moved to Solana Beach CA in the early '80s soon after the establishment of Kaypro computers in that city.
Interestingly both had a relationship to a NLS in there lives.
For Andrew, it was Non-Linear Systems, where Andrew invented the digital voltmeter.
For Alan, it was oN-Line System, where he attended "The Mother of All Demos", which spawned the mouse and some other inventions used in the Xerox Alto, which is where Smalltalk was primarily developed initially.
On re-reading, I realize the name I thought I was remembering is "Andy" Kay, not Alan Kay.
I guess I was victim to "close but no cigar".
