Fear: The Role of Fear in Language Adoption
summary
Argues that adoption hinges on concrete motivating fears — historically Java crossed the chasm by solving deployment at scale — and today concurrency and multicore are the big motivators. Shows concrete tools and wins: Elixir macros + OTP cut boilerplate and let millions of lightweight processes be supervised reliably; Elm signals make UI state pure and testable. Recommends incremental moves (JSON microservices, test harnesses, bridging languages like Scala) rather than an all-or-nothing rewrite.
