Yes that’s my point, and because you want to ‘extend’ to ‘n>1’, this is doubly impossible without picking.
i.e. you literally cannot accomplish this otherwise, even for the simplest case of n=2, with certainty. Since there’s always a non zero possibility of any chosen person becoming much smarter and wiser than you in the future.
Via ignoring the infinite number of futures where they do.
The infinities have the same cardinality. Any consideration of a finite subset still ignores an infinite number of unconsidered possibilities whether n=1 or not.
Besides, any choice you make for yourself has an impact on others in the second order. Ignoring it makes the problem worse. No one is a isolated system, no man an island.
There's always the possibility of going back, re-reading and changing your mind. What's the worst that could happen if you believed that you could make decisions while keeping in mind other people?
