Until few years ago I was a hard-code unixer, witch means zsh+Vim, even if on X11, on modern terminal emulators like Terminator, Tilix etc. Then I've decided to seriously do a thing I've only superficially and never really studied before, after seeing it in action: try Emacs seriously.
In a little time EXWM have replaced my WM, Emacs have integrated a big slice of my previously favorite tools. It's not perfect, it have bugs/flaws, but is so much powerful than the Unix model and the modern GUI model(s) that outshine anything else. I still use zsh, eshell it's a bit too limited/alien to me so far, unix tools lacking a LispM underneath are still serving me under the wood but that's is.
Said that, as you rightly state the actual IT model, VERY unfortunately for the humanity at a whole and no, I'm really serious, have shifted long ago to classic desktop model toward a modern limited and limiting model and now even worse to the old mainframe+dumb terminals model, where the mainframe is external, someone else computer, the cloud and dumb terminals are now "endpoint", utterly complicated pile of crap to boot up a WebVM improperly named browser for legacy reasons. In the actual state of things choice is limited: some "services" can be integrated more or less easily, more or less stably/reliably, others can not.
That's why I've first shared my person journey toward Emacs: even if sit on top of Unix, like a bootloader, not much differently than the aforementioned WebVMs it can wrap Unix and integrate X11/WebVMs (cr)apps a little bit. Doing so does not totally solve your issues, BUT solve partially many of them and gives you something FAR more powerful/evolved than Unix. You can't do much more than that.
To use a truce metaphor: we live in a dramatically lost war, chances to win before dying are utopia at best, but at least we can live the unique life we got a bit armed instead of being totally at the mercy of every enemy. Your car if not today, tomorrow will demand you a login on a smartphone to a cloud service just to open the door, so your WC to lift the cover, your country will demand a smartphone just to pay taxes in an integrated cloud-mobile platform no one really know who really control at a certain "zoom" level, no one can really do anything outside it but you can so far still have a small personal garden that ease your life a bit at least giving a comfortable environment with your data locally available so much powerful that can help cope with the outside world crap.
BTW Slack, a CRAPPY service no damn company should be so crazy to choose it, is supported by some Emacs packages see for instance https://www.emacswiki.org/emacs/Slack as usual it's not a full and bug free support, but you can use it, like you can use Jira etc.
