I suppose that depends on how resource intensive it is and how long it takes.

If you have to go to the teleporter building and wait in a long line, it'll be more like "oops I left at home."

If teleportation is basically free and you carry the device on you, it'll be only slightly worse than walking.

The real bad time is if teleporting is portable and easy to do, but expensive. Then we'll really get ourselves in trouble.

Humans and teleporting have a lot of difficult social problems.

Eh, instant teleportation beats driving somewhere and then having the same thing happen and having to drive back home before remembering. heh

I would love this. Would I be constantly teleporting? Yes. But it would remove the delay between starting an action and getting there

I'd be everywhere, and it would be glorious

me in my kitchen every single day

If I could teleport I would get so fat so fast.

Don't need to be able to teleport to have that issue. Stairs also work flawlessly.
