You are asked to evaluate $\lim\limits_{x \to - \infty} e^x$. However, a trolley is following the path of the function $e^x$ in the negative direction, and Wildberger has tied a person to the $x$-axis at a location ($n$, 0) for any $n \in \mathbb{R}$. Do you choose to evaluate the limit by concluding that eventually $e^x = 0$ and killing the individual, or do you evaluate it such that, while $\lim\limits_{x \to - \infty} e^x = 0$, $e^x \neq 0$?

Consider the fact that if you say $0.999... = 1$, you would indeed be responsible for the death of the person on the tracks.
