AFAIK Pharo technically is not even compatible with Squeak which is where it forks form.��

You assume the code you write will automatically be incompatible to smalltalk-80 but since pretty much a huge percentage of the functionality of Pharo and Smalltalk is in libraries since the language itself is so minimal , I dont think it would be so hard to make your Pharo code smalltalk-80 friendly.��

I advice doing your own tests and seeing for yourself. Then ask questions how to solve problems you encounter. No reason to panic before facing the facts :)

There is a long story about all that.

But to be short:
- if you call it Smalltalk then you have to make it compatible with other Smalltalks. And they are a lot in the 80s��
- we want to make something new and cool what may be not always compatible.

So yeah
