@John Smith 19 Re: The 70's called. Contextual Dependency blah blah...
Excellent post - thanks.
Just one more point. Human beings are remarkably good at deducing meaning from context - and one of your sentences with made-up words demonstrates that elegantly.
"I just drumped a can of lager off Jack" - if I heard one teenager say it to another, it would be obvious that "drumped" is a slang word for "cadged". And I wonder if AI will EVER be able to do that.
