I often think about a rewound reality, where the only difference is the data in my brain... and the biggest problem I have with this is all the people that are born after the time I'd go back to that I don't want to unmake.

Of course, my attention span is terrible, so I never follow one of these long enough or thorough enough to simulate how I'd try to avert such issues... then chaos theory would screw it up in spite of all that. The point is that I concur.
