Nowadays, desktop apps which started in an instant 20 years ago, seem to take several seconds even before they are even doing anything useful like loading a project or whatever. Even things like Visual Studio looking through the MRU project list can take 10 seconds (probably a threading issue) and VSCode, Teams and others are equally unimpressive - in fact the browser, the one thing that should be slow due to the network, is usually fastest when using a well-written site.
I'm not sure whether the multi-platform desktop app was ever a great idea. How much time have we saved "not writing multiple apps" but have instead ended up with slow, bloated software that doesn't usually run multi-platform, at least not all the time in the same way.
