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
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.
