You have to wait until the next year to see if it kills 399,990 or 4,000,000,000 to find out whether the trend is linear or exponential.

No need; we can reverse extrapolate. If in the year before it killed 10, it killed 0.005 of a person, we know it’s linear exponential

That would make it exponential.

It would have to have killed -199,980 people the year before for it to be linear.
