Therefore everybody can see at least X-1 people with blue eyes. You and everybody else knows that nobody will leave the island before the X-1 st day. Furthermore, the fact that nobody leaves on those days doesn't give any more information to the people as it was certain right from the beginning. Why does everybody wait for X-1 days doing nothing? Is there a faster algorithm only taking 2 or 3 days? Or does the solution not work at all, in the end? Let us assume that you can see, say, X people with blue eyes.

I tend to mean all three of these, for related reasons. The Singularity is enough of a wibbly-wobbly, timey-wimey concept that you shouldn’t expect much precision when talking about it.
