Ok, you see, the key is to make certain the matter extrapolators using matter extrapolation see you, in the past. If they do, then you can communicate to them and let them know how to cooperate with you in order to affect events.
how to catch their attention???
...and then I was suddenly a data unit to them, the early extrapolators.
to save this miss-sent email, or to delete it?
in the overall big picture it made a huge difference down the road, say, a few thousand years...
when all other copies are deleted, if I were to have saved it, imagine the consequences.
It seemed I was fortunate to have a common name...
...or perhaps unfortunate, as the case may be.
