In March 2016, someone conjectured on math stackexchange, in a 1-point question, that “Any entire function without zero is constant”. People quickly responded with the obvious counterexample of the exponential function, and explained why the OP’s argument failed.
But in October 2025, if you do a Google search for “non-zero complex function” its AI nonsense tells you, based on that obscure math stackexchange page, that:
“... a key theorem states that any entire (differentiable everywhere) function that is never zero must be constant, often written as f(z) = e^g(z) for some other entire function g(z), notes MathOverflow and Mathematics Stack Exchange.”
FFS Google, turn off this garbage generator and just link to entire pages people can read and assess for themselves, and which (if you put some effort into making your ranking algorithms work *against* the SEO spam and the AI slop) might have a decent chance of being accurate.
