I share that opinion and the ones in your page, but you are making a common
mistake, you must view ST as a language/syntax, but also as an "Object Ambient",
or "Box with objects to play". The language really doesnt matter too much, you
can make other parsers in the Ambient (i know Lisp & Prolog in ST, but not
python). 

By now, the unique "Objects Ambients" that i know are ST and Self, and i think
that CLOS classifies also, but without tools (browsers, etc, or yes?). And
ZOPE a little, but i dont like it too much :)

The really revolutionary thing is the concept of "Objects Box", where you
program / use manipulating objects. 

I think that is the future, if you see the trend in the OS camp, you see that
for example, OLE, COM, and .NET or any component model is trying to reach that.
Also the inclusion of metadata in the filesystems. Or the uniformity of device
access / file access in Unix.

In the end of the road, your computer will be full of objects, not "documents"
and "binaries", all visually manipulable in a Gibson way :)
