Does Jacob actually exist?
I often see a collection of text on this forum signed by someone or something named Jacob,
but I have never actually met the alleged person who claims to be Jacob.
For all I know he could be an elaborate program designed to find every perceived flaw in
scientific theory, or just rebel about things no one else really wants to be a rebel about.
So until an actual human being named Jacob is produced, we must assume that he only
a myth or a program at best, and will remain in the category of pseudolegend until then.
