Well, that's not true either, and the fact that Bill Gates was 
denigrating it implies that he at least knew about it, even if he chose 
not to adopt it (then: of course nowadays Microsoft call almost all 
their technologies "object oriented"; sometimes this description is as 
accurate as when Gates speaks about "our open Windows environment").

We could all make our own choices, but anyone who's been programming 
*seriously* since the 60s will likely remember Simula as the birth of 
many oft he ideas later picked up by Alan Kay and promoted by the Xerox 
PARC SmallTalk group.

I visited that group in 1981 (after Kay left, unfortunately, and then 
being headed by Adele Goldberg, who is now coincidentally promoting the 
delights of Python at conferences like OSCON), and object-oriented 
programming was certainly something that was being taken pretty 
seriously in the academic world as a potential solution to some serious 
PLIT engineering problems.

The fact that it took the technology a relatively long time to appear 
"in the wild", so to speak, is simply the natural maturation of any new 
technology. Given that UNIX was developed in the early 1970s I'd say it 
took UNIX 20 years to start becoming mainstream. But a lot of people 
knew about it before it *became* mainstream, especially those who had to 
place their technology bets early. The same is true of object-oriented 
concepts.

I guess this is just to say that I'd dispute your contention that 
SmallTalk was a curiosity - unless you define anything of interest 
mostly to the academic world as a curiosity, in which case there's no 
way to overcome your objection. It was the first major implementation of 
an entire system based exclusively on OO programming concepts and, while 
far from ideal, was a seminal precursor to today's object-oriented systems.
