That's the point though. It doesn't matter when time travel is invented, only if it can be invented.

If time travel is possible even 10 000 years in the future someone would almost certainly show up at Hawking's party since they have a time machine.

The fact that no one showed up it's a reasonable argument that time travel is impossible

That's like somebody saying in 1912 that fax machines could never be invented because no printouts were magically appearing on their desk. The technology had to be invented before it could be used. If a time traveler has to step out of a machine, that machine has to be invented first. The idea is that backwards time travel would only be able to travel as far back as the invention of backwards time travel.

That being said, from a physics standpoint I can absolutely see backwards time travel as being impossible. We can't move negative distances across spatial dimensions, so why would we be able to move backwards in time?
