The newest Teams app (and I think newest Outlook amongst others) is using system/Edge provided WebViews rather than Electron, which I guess takes care of the “each app gets its own Chrome instance” part of the Electron bloat. It’s so far running better than old Teams for me. On my old work laptop, the fans spun up the second the old Teams client launched lol
It was self-fulfilling for me. I started self-hosting and messing with networking before I went into IT. I thought I’d be in a very different field until ~10 years ago.
