Why do you keep using that expression? Is that like the new "no true Scotsman"?
What else would I use when someone comes up with such lame "predictions".
I don't know of an earlier version of "no true Scotsman" which is a simple type of logical fallacy. The expression I used could be interpreted as a rephrasing of Shlomo Hamelech's: אין חדש תחת השמש, and is more readily accessible without switching input language.
