Nah, this is not harm, this is “basically, way too many people are fucking idiots”. Idiots enough to think that just with "I voted"tm they have done something to really move things toward a better life for everyone

Well… true that only voting does not much help when those who make the rules are not someone you can influence. Also true that abandoning voting is just plain dumb.

Saddest part: I have no answer to the question of how to make a society that works well for everyone with people who do not understand that to ensure wellbeing of anyone the wellbeing of all and everyone must be ensured

Logical and human friendly answer: mutable objects are not a problem, poorly designed code is

Personal rant: why even bother with objects, just use strings, ints, floats, arrays and hashmaps (sarcascm. I have spent hours uncovering logic of large chunks of code with no declaration of what function expects and produces what)

And also, seeing endless create-object-from-data-of-other-object several times has made me want to punch the author of that code in the face. Even bare arrays and hashmaps were less insane than that clusterfuck

I keep hearing about how modal editing is faster

Please, do yourself a favor and ignore that noise. It is more a question of like/dislike and training. Personal sidenote: I daily alternate between PhpStorm and Neovim. Can’t say doing things in either is faster/slower to any significant degree (PhpStorm is mostly there for the things I have not yet configered properly in Neovim, like looking through git history)

and I would like to switch to a more performant editor

This should be looked at and tested objectively: is it working with big files that is the problem? Or navigating the code base? Or something else? Maybe it is better to tweak vscode instead?
