I really enjoy Software Unscripted by Richard Feldman. He interviews well-spoken programmers and skill leaders from a variety of language ecosystems -- and usually the guests share his appreciation for simple, strongly typed, functional and pure functional programming languages (like Elm). Currently Richard Feldman is building a new language and ecosystem inspired by Elm but for non-browser application domains -- and he often discusses concepts and engineering trade offs as related to the design and implementation choices that are being made while growing this (to me quite exciting) new language.
