Comment on If a time traveller posts a video from future, it would probably be tagged as AI generated video

Yet.
It exists in the future.

Doubtful. It’s not compatible with the current laws of physics and would break causality. Also some of those potential future time travellers should have shown up by now.

Causality is just determinists starting with “time travel is impossible” and finding a fancy name for it.
I don’t want to say they’re wrong, just that asserting casualty in a discussion about time travel being impossible is kinda like asserting Godwin’s Law in a discussion about whether or not Trump’s a nazi.

Realtivistic time-dialation says otherwise.

No … it doesn’t. Slowing the passage of time is not the same as going backwards in time.
