Can Learning Smalltalk Make You A Better Programmer?
Slashdot reader horrido shares an article that "has done more for Smalltalk advocacy than any other article in memory." It was the second-most popular article of the year on the Hewlett Packard Enterprise site TechBeacon (recently passing 20,000 views), with Richard Eng, the founder of the nonprofit Smalltalk Renaissance, arguing that the 44-year-old language is much more than a tool for teachers -- and not just because Amber Smalltalk transpiles to JavaScript for front-end web programming.
It's a superlative prototyping language for startups. It's an industrial-strength enterprise language used by businesses both big and small all around the globe... Smalltalk's implementation of the object-oriented paradigm is so excellent that it has influenced an entire generation of OO languages, such as Objective-C, Python, Ruby, CLOS, PHP 5, Perl 6, Erlang, Groovy, Scala, Dart, Swift, and so on. By learning Smalltalk, you'll understand how all of those useful features in today's OO languages came to be.
The article also argues that Smalltalk pioneered just-in-time compilation and virtual machines, the model-view-controller design paradigm, and to a large extent, even test-driven development. But most importantly, Smalltalk's reliance on domain-specific languages makes it "the 'purest' OO, and one of the earliest... It is often said that programming in Smalltalk or Python is rather like Zen; your mind just flows effortlessly with the task. This is the beauty and value of language simplicity, and Smalltalk has this in spades... Smalltalk, by virtue of its object purity and consistency, will give you a profoundly better understanding of object-oriented programming and how to use it to its best effect."

Having developed applications in Smalltalk I can say it had some major failings too. Serious development absolutely required Envy Developer otherwise it was impossible to deploy into a team environment (there are no files to share).
It also was nearly impossible to deploy standalone applications. You had to strip out the development environment, and other objects not necessary for production. Take out too much and sometime later you get a "not implemented" error.
All of its deficiencies could have been fixed eventually but very few companies outside of educational incubators really bothered. The Smalltalk industry was rife with overpaid contractors.
