the main thing that confused me with JT was his talk of the world line.
In my opinion this was one of the holes in the JT story. He claimed that all realities were occuring at once. he had traveled from his timeline into
a time line that differed from his by less than two percent or something like that.
When he traveled back to the future he would not be traveling back to his own future but a very similar one where another John Titor traveled back in
time to receive the same early IBM machine...supposedly.
If in fact you are bopping around from reality to reality you are in fact not fixing or changing anything in your own specific reality, who is fixing
your reality while you fix anothers. It is a bit silly.
Of course when people would ask specific questions about the future he would either condescend saying that they shouldn't asks specific questions
about sport scores because they just wanted to bet on the game. Other times he would claim that it would not be a good idea to share information
about the future with those from the past.
The main problem with this answer being that if you are not from our specific future timeline, your future may not happen to us and of course if John
had passed on specific information it wouldn't really matter because he came from a different reality.
One or two percent may not seem like much, but when your talking realities and timelines one or two percent could mean the difference between
evolution and hanging from trees with our tales.
John was clever, just a little too clever for his own good I think it was a prank that got out of control. Though it's been a while since I read the
stuff.
