Jonathan Blow's LambdaConf 2025 keynote demonstrates the Jai programming language and explains its design. It includes demos of metaprogramming and tools that visualize programs.

A 10-minute clip from a Jonathan Blow Twitch stream in which he argues that game engines do not really need separate scripting languages. He questions the value of embedded interpreters when the main language can do the job.

Jonathan Blow demos his prototype programming language, covering the base language and compile-time execution, including running a game while compiling. The video is about 70 minutes of demo followed by Q&A.

Rich Hickey presents an extensive introduction to Clojure at the Boston Lisp meeting, assuming prior Lisp knowledge. It covers the language's design decisions relative to other Lisps.

Scott Meyers' keynote at DConf 2014, drawing on 25 years of C++ experience to offer the D language community a plea about what it should avoid. It centers on the accumulated complexity and pitfalls of C++ as a cautionary tale.

Evan Czaplicki, creator of Elm, examines how programming languages are funded. He looks at where compiler engineers' salaries come from, why Go has about 5 engineers while Dart has about 30, and how this limits language design.

A 13-minute OSCON 2010 talk in which Rob Pike argues about what is wrong with mainstream languages like C++, Java and C#, and presents Go as a response. He discusses verbosity and what lightness means in a language.

Scott Wlaschin's NDC Oslo talk on four 1970s languages, SQL, Prolog, ML and Smalltalk. It explains their philosophies and what practical principles they still offer modern developers.

Evan Czaplicki, creator of Elm, gives an elm-conf 2016 talk on the non-code side of building a language. It covers the philosophy behind Elm's development approach, including batching work and the priorities of different language communities.

Chandler Carruth's CppNow 2023 talk describes Carbon as a successor language to C++ rather than a superset, focusing on C++ interop and a path to memory safety in large existing codebases. It explains why Carbon takes a different approach from Cpp2 and Circle.

Rob Pike opens GopherCon 2014 with a keynote on the design and evolution of Go. He covers where its ideas came from, including the origin of hello world.

ThePrimeagen interviews Chris Lattner, creator of LLVM, Clang, Swift and Mojo, with TJ DeVries, in a long live-streamed conversation. They discuss language design and Lattner's experience building Swift.

A GopherCon 2014 session where Blake Mizerany replaced his planned talk with a panel discussion with members of the Go team. It covers Go's design choices and community questions.

Julia co-creator Jeff Bezanson candidly lists fundamental problems with the language at JuliaCon 2019, including modularity, types and compiler latency, and how they might be solved.

Java Language Architect Brian Goetz talks at a Clojure conference about the challenges of evolving a mature language like Java while preserving compatibility with existing code and developer expectations. It also gives a look at where the platform is headed.

Stefan Karpinski's European Lisp Symposium 2016 talk asks whether Julia is a Lisp. He covers the features it borrows from Lisp, such as macros and closures, and where it departs, including syntax and its type system, with generated machine code shown.

Rob Pike's dotGo 2015 talk argues that Go only seems simple, and that its simplicity hides real complexity that is part of the design. He explains the thinking behind Go's restraint in features.
