"The Economics of Programming Languages" by Evan Czaplicki (Strange Loop 2023)

Caption notes

At Strange Loop 2023, Elm designer Evan Czaplicki reflects on the work of maintaining a language. Beyond the compiler, there are releases, package infrastructure, documentation and community work. He compares models such as company patronage, consulting, research grants and hosting to ask who pays and how funding changes the tradeoffs around adding features and sustaining a project. He argues that open code can lower switching costs for users while a small team still bears the cost of developing both the language and a business. The talk ends with an open question: how can users keep the option to switch while small authors have a viable path to sustain their work? This guide follows his experience and conjectures at the time. Financial estimates, industry scenarios and an unreleased prototype await independent verification.
