Well, I'm usually the person to quickly point out that HN is very conservative, and advocate the modern UI/tech stack that HN thinks is too flat or too bloated, etc... But as a long time macOS user, I can't say that the UI is good. If I can fix one thing from the new UI, I think it should have borders or at least a different background color, like pre-iOS 13 with button shapes. The current iOS buttons (and the new macOS design) doesn't give any visual cue for the user to know whether this is an icon label or a button. That's a problem, and one that macOS has solved elegantly by having different textures (like the toolbar). It's now... more like Windows 10 where everything is on a flat surface without any differences.
