In this episode I talk with Bartosz Milewski. We talk his introduction to category theory, teaching category theory, comparison of Monads and other composition patterns in functional programming to composition patterns in object oriented programming, and finish with some philosophical thoughts on category theory.

Bartosz’s videos on category theory on YouTube
How Bartosz became exposed to category theory
Elegant code, and what does it mean for code to be elegant?
Exposure to functional programming through C++
Template meta-programming in C++
Andrei Alexandrescu’s Modern C++ Design: Generic Programming and Design Patterns Applied
Translating functional solutions in Haskell to C++
Exposure to category theory
Categories for the Working Mathematician
Understanding category theory through examples
What clicked about category theory once Bartosz “got it”
“Category Theory can be simplified to just two things, composition and identity”
Futures in C++
Futures are monads
“Monads are just about how to compose stuff”
Bartosz’s posts on Futures
– Broken promises–C++0x futures
– Futures done right
– C++17: I See a Monad in Your Future!
“You cannot design a good library, if you don’t understand category theory, or at least elements of it”
Category of Types and Functions
“A composition is the essence of a category”
“A monad is a way about composing side-effects”
Category theory patterns become hard to understand because they are so general
Function composition in an imperative language
“A monad is the overloading of a semicolon”
Background of attendees in his courses
Interest in teaching category theory to artists and other domains
“You take a concept from logic, you can translate it almost mechanically to a concept in programming, and visa versa”
Philip Wadler’s keynote on Curry-Howard Isomorphism at LambdaDays 2016
Bartosz’s Curry-Howard-Lambek Isomorphism at LambdaDays 2016
Imposing structure on the universe because that is the only way we can understand stuff
Wondering if “mathematics is just the way of studying our minds rather than an objective reality”
“If category theory is the study of the human mind, then everything must follow the laws of category”
Possibility to take category theory and explain it using examples from other domains
Introduction to Category Theory talk as a starting point
How useful it is to learn category theory???
“I think that getting this higher-level view […] drives you to better solutions”
Importance of keeping your mind open because you never know when something will be useful
