Where are all the maglev trains in non-capitalist countries? Sooner or later, in any system, someone has to do a cost benefit analysis and decide whether it’s worth it. It’s not just about profitability. There are plenty of situations in the US where something is unprofitable but still funded because the benefit is worth it.
VSCodium, emacs, vim/neovim, helix.
Helix is pretty slick, but it’s not very extensible. Very easy to use and if the out of the box features are good enough for you then it’s a fine IDE.
Neovim is my preference unless I’m working with Jupyter notebooks, in which case I switch to vscodium. It’s a pain in the ass to set up. I took the easy way out with LazyVim. It’s fast to work with and I can use it for almost everything.
I dabbled with emacs many years ago. It’s like vim but completely different. You can make it do anything. Personally, I don’t care for the keyboard shortcuts. It’s probably easier to pick up than vim, but all the key chords and sequences are too much for me. In any case, anyone willing to look at vim should also take a look at emacs.
VSCodium is accessible and extensible. You can’t go wrong with this one. It can’t refactor like the Jetbrains stuff, but if there’s anything else it can’t do then I don’t know what it is. It’s a great IDE.
Really, any of these can do just about any job and do it very well. There’s no choice that clearly stands above the others. It really comes down to personal preference.
