“But that assumes that these ‘future’ people would ALWAYS feel that way about revealing themselves, each and every one of them, eternally for many, MANY millenia, eternally, forever and ever nd ever. No one in this future, with time machines in existence, would EVER reveal themselves to those in the past? EVER?!”
Your premise is flawed. You assume that if time travel will be or has been invented then you must have personal knowledge and awareness of time travelers from the future. What if it exists but is too expensive to be ubiquitous? What if it is highly dangerous?
Look at human travel. Walking is built in. A bicycle is more efficient. A horse is more so. A train has advantages. Cars using combustible engines offer more. Then comes planes. Then jets. How about breaking the sound barrier?
Have you ridden on an aircraft capable of doing Mach 3? Would you know if they exist from personal experience? How about craft capable of reaching outer space? Landing on the moon? Mars? Interstellar?
Notice how these all require greater technology, efficiencies, and money?
What if time travel is invented a year from now but costs a billion dollars per second to transport one person? No one on earth can afford to return to today. And even if they could why would they? And why would they make their presence known to anyone, let alone you or me?
What if time travel requires great precautions to avoid creating things like feedback loops that can become highly destructive? When we put a man on the moon it was not a suicide mission. We brought the crew back. We didn’t allow them to be killed by radiation on the journey. See how a time travel mission could become far more complicated than your binary choice allows for?
I met a missionary to New Guinea who was there and received news of our successful mission to put a man on the moon. The primitive natives he lived with said he was lying because they looked at the moon and didn’t see anyone. They said however that he was a great liar (storyteller) who was worth coming to hear.
No one was trying to hide this event from the natives. They just weren’t prepared to grasp how it was possible. The average person enjoys many advanced technologies that they have no understanding of in terms of the underlying functionality. They just know they work. They don’t know how.
There might even be the possibility of time travel which only works with a combination of transmitter and receiver. In this scenario, it is only possible to go back in time to the point where a receiver has been invented and built. Perhaps this combination will be invented in the future.
I’m not arguing that humans have or will ever time travel. I have no firsthand experience to support this, just like you. I’m just saying that your argument against it is too simplistic.
The mere fact you have to go to such great verbal lengths in an attempt to disprove my point disproves your theory.
I stand correct.
