Neither v^2 nor v^3 is exponential. They are polynomial functions. Exponential would be if wind resistance or power or fuel consumption were c^x for some constant c.

It seems to have become fashionable to say "exponentially" or even "EXPONENTIALLY" when you mean it's a rapidly increasing function, but to the technically-minded, whom I would hope to find on HN, there is still a clear-cut difference between exponential and polynomial.

I think the fact that polynomials contain an exponent forgives that particular degradation of precision in the vernacular. I corrected the OP by adding context so onlookers could know just how fast the power requirements grow without poo-pooing their choice of words. In a programming context, extacting language precision is beneficial. Shooting the shit in an Internet forum I think we can tolerate imprecision in others without causing a dust up. Now tell me how do you feel when someone says “it’s pretty unique”
