Yes, thats why exponential curves taper off to an S-curve in the real world (e.g. population growth is exponential at first, then tapers off when hitting food limits). This article is about estimating the more realistic s-curve in the real world. The point it: You cannot get a sense of the end by observing the beginning... even in the super idealized case of the data coming from a perfect s-curve, let alone the real world. Its a great article.
