If you released software that was exponential, but your QA department only ever tested small inputs, I think it would be negligent to omit to your boss and|or clients the rate at which run-time could expand.

and I think it would be a horrible manager to not care about the difference between a day and a second.

Yeah I agree but my point is none of what you are talking about has anything to do with O(), which doesn't attempt or claim to do what you want to do.

It's like someone gave you a hammer and you're saying it's broken because it doesn't cut wood very well. It's not designed for that.
