Hi Gilad and all - This is a worthwhile topic, one to which I intend to respond, but it will take some time. Let's start by renaming the thread...
If I may, I'll make one more observation. This thread (and similar ones, oft repeated among Smalltalkers) bemoans the fact that others do not see the beauty of Smalltalk. What I liked about this thread was that Smalltalkers were engaged in serious self examination. There seemed to be a realization that some things need real changes.
Perhaps as part of this self examination, one can see how hard it is to get out of one's comfort zone. The effort of engaging with and learning something different is more than most people can find the time and energy for - even when the differences are relatively modest, as in the case of Newspeak. Some of the reasons some of you cannot get around to really getting involved with Newspeak are quite analogous to the reasons why your Pythonista or Java (or whatever) colleagues cannot get serious about Smalltalk.
I am well aware that this is not a terribly actionable observation. It's just the way it is. What one can do is identify weaknesses and work hard at fixing them, and hope that some people will find it worthwhile to become truly involved.
