As a certified noob to Smalltalk hailing from the Ruby, Delphi, .NET and
Java worlds where RDBMs rule, I must say I'm amused how anyone can say
Smalltalk has *failed.*
I had a funny experience when doing mainly Rails development a couple
years ago. I had an interview at a PHP shop, where the main technical
guru there insisted that Ruby/Rails had "failed" and wanted me to tell
him why. I told him, actually, there were bugs in the early ActiveRecord
API that exposed Rails to scalability problems, not the framework or
design concept itself. I pointed out that if Rails failed, so did
Symfony, and Django, ASP.NET <http://ASP.NET> MVC, and countless other
copy-cat frameworks in other languages/platforms. If one measure of
failure is industry adoption, then there was no way Rails failed.
And where did MVC come from? Well, we know that answer. The whole
discussion is pointless. Engineers sometimes get the idea that because
they or a project they were on failed that happened to be using a
particular tool, the tool is a failure. At bottom, this guy was bitten
by Rails and so he had a kind of vendetta against it. As if PHP is the
way, the truth and the light. By the way they offered me a job anyway,
but I didn't take it. :)
Some tools make certain things harder or easier. I find Smalltalk
liberating as it makes it easy to decompose hard domain problems sans
all the syntactic cruft of the so-called modern languages -- which,
funny enough, are constantly trying to find new and more complicated
ways to express what Smalltalk has always done simply: generic
collections, metadata, reflection, etc.
So, I'm going against the grain and getting into Smalltalk. I have been
a bit disappointed by the state of certain libraries and the relatively
small community, but I enjoy the language and feel more productive in
it, so...that's what matters to me.
