Re: But it actually looks nothing like macOS
That is not a fail, that is a win.
The guy specifically states it's about returning to the simplicity of 90s computing, including GUIs which actually followed rules which were based on useability studies. You learnt the GUI, you could use every piece of software there was.
I realise this sounds like "old man yells at cloud" but I can't see how present-day GUIs are an improvement on that. Practically every piece of software is different today, huge areas of screen estate are used up for no good reason, the response time is abysmal, items in lists move around just before you click on them so you click on the wrong thing, badly contrasting colours and fonts hide information from you, not even the OS designers can follow their own rules. Bah humbug.
