Static types
Why use static types?
Correctness 1
Adding types does not make correct code more correct
Speed 2

Maintenance 3
Adding complexity does not improve understanding
Ruby is a better choice
Programming is too hard
We are too slow
We fail a lot

Assumptions help us solve problems
Assumptions hinder our efforts
Technical debt Cost to experiment
Refactoring Rework
We live in a world filled with hard problems
Let's make programming easier
Let's test our ideas more quickly
Let's fail more productively
