Until special relativity kicks in to completely invalidate whatever intuition you have about this problem.

How is this a joke?

Knowing exponents and how to apply it is not the same as having any intuition about what the actual value of a certain exponential function will be at a certain point and when it crosses a threshold.

There’s no exponential function involved, which is why this is easy to intuit. A true exponential function would indeed be difficult to intuit.
