[squeak-dev] Smalltalk for small projects only?

Hi all,

Programming in the large with 50 or 200 programmers...
This discussion illustrates that we have moved a long way from Alan 
Kay's vision of the Dynabook; "/... a laptop personal computer for 
children of all ages/". A personal computer that contains my personal 
data. Data that I own and manage with personal programs, some of them 
written by me. Smalltalk was targeted to be the software system for the 
Dynabook. A single programmer, often myself.

I have followed this list for some years now, and I miss greater 
interest in the ultimate end user of the software; the human. I am 
working with many others on a paradigm that puts the end user in the 
driver's seat. A paradigm based on objects (not classes) for mental 
models that are shared and understood by end users and programmers 
alike. A paradigm that models the realization of use cases. A paradigm 
that leads to models that can be faithfully implemented in software to 
ensure that there will be no surprises.

The Squeak environment is essentially based on objects and is an ideal 
starting point for implementing new paradigms. The Squeak programming 
environment has to be extended with facilities for describing how 
ensembles of objects interact to achieve a common goal. It's easy to do 
in Squeak. So why not?
