Very good, crystal clear.
Maybe a bit too slow in the description of the receiving algorithm, but this is just "my taste" (and a little detail), sure a 5 stars talk
Excellent talk!
I really liked the ideas that got spread. I did not know how Alan Kay invisioned OOP.
It could have been a bit longer and maybe with hints to languages like Objective-C (which is influenced by Smalltalk) or Python/Ruby.
They practice these things, even if they lack features in other parts of the language. ;)
I would have liked if there would be less code and demo and more information on real world experience with Haskell in the field of data science.
Otherwise it was informative on which packages are out there.
