The notch exists (in it's huge and ugly form) because Apple failed to incorporate Touch ID (it's first choice, by all accounts BEFORE they had to settle for Touch ID (at which point of COURSE they started to hype Face ID... what choice did they have? Admit failure?)).
No doom and gloom. Apple just tried and failed. It happens. Face ID is the consolation prize, but it'll be fine. I just wish it didn't necessitate a gaping notch.
It isn't a "myth". Apple scrambled for an alternative after failing to incorporate Touch ID. Face ID is our consolation prize.
