Apple's whole thing is "computers for non nerds".
Nerds would type SOS at a command prompt.
That's why Jobs-era iPhone always visually AND verbally instructed "[→] slide to unlock", where nowadays it's just a ───── at the bottom that are supposed to be extremely discoverable and immediately obvious and magnificently intuitive.
People can’t interpret that kind of nonverbal/abstract cues. It’s quite an inner circle thing of nerds that those seem ultra obvious.
