There absolutely lies value in studying programming language, but maybe not when reinventing ideas of the past. > I encourage everyone to create the most absurd, implausible, and impractical languages. Chasing the measurable is often useful, expressing the expressible is insightful, but never forget the true goal of language design: to explore and create what isn’t. Sorry, but this sounds more like an artsclass to me. Don't get me wrong, there was a point in time where exploration of the unknown was the only way to move forward. But these days we would need greater insights into higher-level language semantics and inherent tradeoffs to guide language-design and language evolution. There is plenty to choose from and one can learn already so much just by reading up on the Java-EG mailing lists. Brian Goetz has a true academic mindset and I frequently feel inspired when I read his reasoning which is both highly structured and accessible. Otherwise we would just be left with another compiler class. Compiler basics really aren't that difficult. |

Indeed, it is, and that's the point! Being interfaces to computers for humans, programming languages sit at the intersection of computer science and humanities. Lots of people like to treat programming languages like they're math class, but that's only half the picture. The other half is usability, ergonomics, learnability, and especially community. Not to mention the form of the language is all about aesthetics. How many times has someone on Hacker News called a language "beautiful" or "ugly" referring to the way it looks? When people praise Python they talk about how easy it is to read and how pleasant it is to look at compared to C++. Or look at what people say about Elm error messages versus C++ template errors. Actually a lot of what's wrong with C++ could have been averted if the designers had paid more attention in art class.

Here's a talk that argues there's much more fertile languages ground for ideas outside of the "programming languages are math" area, which has been thoroughly strip-mined for decades:

This author takes the perspective that programming languages are much greater than the sum of the syntax + semantics + toolchain + libraries, and treating them as such is limiting their potential.
