There is this memo video of S. P. Jones that famously says "Haskell is Useless". I love Haskell, but I wished it was universal like C, C++, JavaScript, Rust, and C#. By that I mean: It could be used to create apps for desktop, mobile, and web. JavaScript can be used to do so many things like power the entire web, be on node and let anyone create cli and share the code with web, and mobile through React Native, on desktop with Electron and its alike things, it lets you do plugins for god knows how many things, it lets you write things for the GNOME Shell... C and C++ are perhaps behind everything in the world and string theory finally gets seen will see they are written in C. And they can be compiled to Web and almost everything in the world. Rust is a placeholder for the two, and C# reinvented itself when it saw Mono and now works even in the browser. Each time I see Haskell I wonder what else can I do rather than creating CLI apps, and it makes me choose something else that grants me more code reuse and interesting applications.

If I could have a vision for Haskell, it was for it to be useful. Academic research and making compilers is cool, a few cli things here and there are cool too, but why can't we build music players and game engines and flutters and web pages with it? The language is way more elegant and beautiful than all the JS/C like languages out there and I really wished I could use it for the things I did. I'm aware of Servant/Yesod/IHP/Miso/Reflex for web, GTK/Monomer for desktop, TidalCycles for music, SDL/gloss for games, and various FFI/plugin, but none of them feel as coherent and worked on as the others, none of them are polished. Haskell surely needs good DX, but it also needs really better reasons for existing.
