Everyone who dies has probably used a smart phone or the internet so lets start the avalanche!
Besides that, all people still currently living have not died.
Parent didn't put it in time terms. Just noted that everyone who ever lived, has also died ("A && B", as opposed to "A then B").
>Besides that, all people still currently living have not died.
Yes, though one could say that those people are still "living", not yet in a state having "lived" (past tense), as parent put it.
You might have e.g. "lived in London" (if you don't know, so it's a settled thing and a specific period of your life). Or "I've lived in poverty", etc.
But "I've lived", period, without such a qualifier is not that common or useful when one is still alive.
In this case, though, it's not "Everyone who has died has died", but "To have lived means you're dead".
The same way that "to be a corpse means that you've died". That's not a tautology (it's not "to be a corpse means you're a corpse"), just informs us of a prerequisite for the other thing to happen.
Either way, the statement as given does not support the unstated implication that everyone now living will eventually die.
Arthur C. Clarke wrote "Behind every man now alive stand thirty ghosts, for that is the ratio by which the dead outnumber the living." I wondered if that ratio needed updating. It does, but not, it seems, in the direction I expected.
