An uncertain factor is the influence of human technology such as climate engineering, [2] which could cause significant changes to the planet. [3] [4] For example, the current Holocene extinction [5] is being caused by technology, [6] and the effects may last for up to five million years. [7]

Assume, for simplicity, that the total number of humans who will ever be born is 60 billion (N 1), or 6,000 billion (N 2). [6]If there is no prior knowledge of the position that a currently living individual, X, has in the history of humanity, one may instead compute how many humans were born before X, and arrive at say 59,854,795,447, which would necessarily place X among the first 60 billion ...
