Michael Feathers: Hierarchies of Stability - Robust Systems and Fragile Code

The spectrum of languages we can choose from has never been wider. We can work in languages like Haskell and Elm that push forward with static verification and ones like Python, Ruby, and Javascript that make little to no attempt to provide static typing. Both classes of languages are used effectively in production, and that should make us suspicious about the claim that static typing is necessary for safety.

In this talk, we will examine a model of safety that borrows from Nassim Nicolas Taleb’s view of fragility, robustness, and antifragility and consider whether we can make safer systems with fragile parts.
