I'm sorry, I have a lot of respect for Joe Armstrong but this is simply something he got wrong, probably because he didn't fully understand smalltalk objects.

I'm sorry, I have a lot of respect for Joe Armstrong but this is simply something he got wrong, probably because he didn't fully understand smalltalk objects. Before he 'admitted' as such, he understandably thought OO was stroustrop style OO. Then someone pointed out to him that originally OO was smalltalk OO, which admittedly looks vaguely like erlang message passing. But there are critical differences.
