Can be more of one reason, e.g. ... because people are still thinking
in bootstraping... a new genesis... something irrelevant in terms
of open systems (ambience), like Smalltalk.
Under the point of view of systems where semantics can change,
the genesis is only anegdotic. It is more important the sustainability
of the system itself (the persistence of the self... when contents
change through time), the survival in case of accidents (after
sensing damage), and the preservation of identity (been known
as the SAME systems after changes).
Many syntax can coexists, and it is related with diversity of
expression; not with ideals (a mother language/syntax
to make the first spell).
The change of semantics though actions "outside" the system
itself make us continue writing programs. oops!
the Program class is still missing! :-P
IMHO, changes in core semantics and the effects of doing the
changes in the system should be promoted, because
are important evidence to recognize smalltalk as an open
system and not as another OO language (the contrary has
happened during last years, insisting in the importance
of the "code").

Image as the snapshot of a system, contains representation
of objects.. in text or binary; it is only what has been
stored from a system in the past.
It is as important as a snapshot of a woman.
I prefer to invest my time gaining experience with the living woman.
People that write good poems (code) are forced to
write another, tomorrow.
Ah!....
Another reason for "computer revolution didn't happened yet",
can be because people still think in terms of computation,
as systems are still made to compute something.
cheers,
Ale.

can anyone tell me, when last time he had to deal with hardware, which
having no preinstalled operating system/BIOS up and running,
or there only C compiler and no any other languages which can run on it?
P.S. i think i know the answer to question why "computer revolution
didn't happened yet",
because every time people inventing something new, they implementing it in
C.
