Smalltalk turned 50; A pure Object Oriented programming language with amazing ideas from 1972

Sometimes we fail to understand how old some technologies are. This september Smalltalk programming language turns 50! And it was a pure object oriented language from the first day (in 1972). In this short video I'll do a quick review on some of Smalltalk's features and will try to encourage you to spend a couple of hours and write some basic programs with it. Its fun and has lots of amazing ideas.
And for sure, at the end we will talk about why this amazing language did not conquered the world!

Fascinating. I'm retired and enjoy playing with languages...this is definitely for me to investigate. Thank you for your inspiring video.

Smalltalk needs to make a comeback.

Excellent video! Clear, concise, and straight to the point.

3:42 Worth noting that metaclasses in Smalltalk are a bit different from, say, metaclasses in Python. In Python, multiple classes can be instances of a common metaclass, while in Smalltalk, each class has its own metaclass. The metaclass serves a different purpose in these two languages: in Python, a metaclass takes care of creation of its instances, which are classes. In Smalltalk, the metaclass is a holder for what Python calls classmethods.

Can someone please explain me better what 00 is? I didn't understand because English isn't my first language

actually Pharo is really active nowadays

Actually, there were four prominent celebrations for Smalltalk last year! Among them: www.youtube.com/@50yearsofsmalltalk.

Despite the cost, Smalltalk actually acquired the second largest object-oriented market share in the 1990s, after C++. Smalltalk is VM-based, just like Java, C#, Python, Ruby, etc. It doesn't have to be slow; it's a matter of making the effort to optimise the VM.

nah, I wouldn't call it OO, Erlang goes more in line with the definition of OO that Alan Kay gave than Smalltalk, but Smalltalk is what it is because it was Alan playing with what it was available at the time, Smalltalk is like the first car in history, it still looks like a horse-pulled cart with some quirky stinky machine. Smalltalk just copied Simula modules and call them classes. It was Carl Hewitt who materialize in the Actor Model the nebulous ideas of OO that Alan Kay described. Of course then it was CSP, which just offers a different taste to AM but is equivalent, then you have the real improvement ConcurrentML. the Actor Model is like a Corvette of the 1950s, CSP is like a Mustang of the 1960s & ConcurrentML is like Tesla.

Everything truly is an object, though. How can you get more object-oriented than that? Numbers are objects, functions are objects, classes are objects, and you communicate with them all by sending messages.

[@acasualviewer5861]

Dude.. Alan Kay coined the term "Object Oriented".. Smalltalk is the definition of OO.. all others are copies. Erlang may be an improvement. But that's another story.
