If you stepped through a time-travel portal, your conscience would effectively not exist between the original time and the time the portal leads to, yet no one would call you dead. If you could somehow install your mind into a new body, let's say you download it into a flashdrive and plug it into someone else's brain while your original body lays without a mind, people may call our body dead but not you. So when there is a continuity of self between the person who steps inot the teleporter and the person who steps out, I will never call that a death, that's silly.

Always reminds me of one of my favorite books (part of a series) The Collapsium by Will McCarthy. A big part of the book is their version of teleporting which does involve destruction and recreation, but while you're at it you could make more than one copy at the destination...

If your consciousness exists right down to conversationally-induced existential dread, what do you care what or where the substrate it exists on is?

Read the "The Punch Escrow". Not star trek but well worth it if you're into this sort of thought experiment.

Just need to think like a dinosaur.

Reminds me of that CGP Grey video elaborating on the same idea https://youtu.be/nQHBAdShgYI
