Seargentbig: people are discussing backwards time-travel as it is the more difficult and interesting direction. Travelling forwards is as simple as either (a) cryogenically freezing yourself and waking up in the future or (b) travelling away from earth at near the speed of light then returning. Before anyone says anything, I know these are impractical, if not impossible, but they're TV-Dinner compared to travelling backwards.
The "we haven't seen time travellers yet" proof against time travel is fatuous when you take into account that pretty much every theory regarding backwards travel necessitates that the time machine must exist in the past for you to go back to it. E.g. you must have one half of a linked wormhole-pair for you to enter the other half in the future.
