Casual emacs user since 1991, and from my POV ... it seems like maybe a confluence of things (lsp, treesitter, etc.) is bringing some people back into the Emacs folds.

For years emacs is what I used for C/C++ coding. Then CLion came on the scene, and it would be very hard for me to walk away that from and train my fingers back to meta super land. But it does seem like Emacs is getting competitive as an alternative to IDEs.

My new job is all in Julia, and I suspect emacs will provide a better experience for that than a Jetbrains IDE. I'll give it a whirl.
