I mean, I'm always reading questions about whether time travel could ever be possible, how it would be achieved, and what the consequences would be.
But now I want someone to tell me how humankind would benefit. For this, you have to suspend disbelief. So we're assuming that it is environmentally sustainable, that it's possible to travel in both directions along the time line, and that by visiting the past, we don't impact on the present.
BTW, if you accept that last point, then you have to concede that anybody who did visit the future, then returned to the now, could have no impact on that future already visited.
So let's go.
