It is things like Qt that only HN and online nerds care about.
Don't get me wrong: I really like well made native apps and I think they're great. But Qt isn't as great as software made with native toolkits directly.
The primary advantage of web apps is "zero install", which is a major point of friction at large corps.
Citation needed. Currently working in a jQuery+Coffeescript app that still works like a charm.
No it doesn't, the HTML spec hasn't changed, whereas QT has. The issue is how the webapps were built in the first place. You don't need Nextjs and all it's friends to post a form to a backend once an hour but somehow that is becoming the standard approach...
For macOS check apps made by Apple (Logic, Final Cut), Panic, Rogue Amoeba, or apps like Pixelmator, Affinity, Pixelmator, TablePlus, Tower, Dash... there's more.
There's even open source ones like IINA providing a premium look+feel.
