Cell phones have come fairly close. Even the Amish use them. Can you
think of a culture that has rejected them?
"Clinic Seed" style uploading might do it as well.

Here is one.

Hugo de Garis has the idea that unfriendly AI will be the end of us.

But AIs could travel to the stars with relative ease. So that means
you need a reason for every single one of them to be stay-at-homes.

1 Something (like speed of light) keeps them all at home (or in a
dimension, black holes, cyberspace) where they are not apparent.
2 Something destroys the lot of them. (Functionally same as the above.)
3 We are the first. (Unlikely as this might be, someone has to be the first.)
