Web applications are a bit more complicated, but that complication is self-inflicted. We developers choose to to hijack users' devices for work that should be done on the server in the name of providing a better user experience, and we make our work harder in the process.
I think you are absolutely right with "self-inflicted" --- it brings to mind the frequent discussions here about Slack and their web-based client using hundreds of MB to gigabytes of memory for what is essentially "IRC with some images". Not too long ago they "stopped supporting" older browsers, which was basically a kick in the face to everyone for whom it was working perfectly fine before.
I remember using "webchats" in the late 90s/early 2000s with IE6 (or could be 5/5.5, not sure) on machines with probably 1/100th the processing power and memory of ones today, and they worked perfectly well; complete with things like animated emoticons (they weren't called "emoji" yet) and GIFs that didn't even lag the system unlike what happens today, and that was on a single-core CPU!
A possibly fun project is to create a Slack clone that works with that resource constraint, and uses their API; they have a WebSocket interface which older browsers are obviously not capable of using, but I believe there's a classic AJAX API too.

Use a Matrix bridge if you really need Slack, and pick one of the web-based Matrix clients, or build your own. Some are extremely lightweight.
