Anyone capable of time travel has thought about it a lot. Whether to go forward in time or backward is a central question.
If the past cannot be changed, or it is extremely dangerous to do so, travel to the past becomes tourist travel at best, an exercise in voyeurism - look but don’t touch.
Far more interesting would be to travel forward in time. Great wealth & power could be gained today by knowing what will happen before it happens. But would that trump time travel itself? The marvel of seeing the future might tempt the traveler to see even further into the future. Like a kid at Disney World, leaving is not an option. Having done this a few times, history - the past - becomes ever more boring. Why ever return to the “present” when the future is so much more interesting?
This is why you never meet a time traveler. They are 10 million years ahead of you. You don’t know about them, yet, & probably never will.
