PS: also looking around, there seem to be plenty of laptops with thin display bezel and no notch, if others can do it, why not Apple?
Because those laptops have worse webcams.
You don't have to agree with the tradeoff Apple made, in fact I don't, but I think the reasoning is pretty clear.
The extra room in the notch is likely there in case they want to change webcam parts to something larger, add Face ID, etc so they don’t also have to change the display panel and can continue to use existing stock.
Apple seems to like to try to avoid changing parts/tooling wherever possible and will go as far as to awkwardly keep using a chassis until stock of that part has been exhausted if necessary (see the 13” M1 Touch Bar MBP).
Yeah, I'm thinking firing Johnny Ive wasn't enough.
The notch feels weird, but when I try to redesign it without sacrificing features, I can’t come up with a better option. …Not that I’m a brilliant designer by any means.
I'm convinced this is true, at least partially.
The iPhone notch is branding and a visual differentiator from the competition, which is Apple's forte, and carrying over that very distinctive design element to other product lines seems right in Apple's playbook.
In other words: glass slab in your hand? Who knows. Glass slab with a black notch? iPhone.
Person typing on metallic laptop in a cafe? Who knows. Ah, but the screen has a notch? MacBook.
