We take these things as being "normal". But sometimes newbies say the darndest things. A while back, I had one ask me the question (paraphrased) "We know from long experience that hardware capabilities are increasing geometrically. And we have a good idea what that geometric rate is. Why don't they just build computers and software accordingly?". And I've got to admit, he had a point.
I've already had enough of dealing with silly "limits" to last a lifetime. Current rate of change doesn't matter. It's the first derivative that does. The second has always remained remarkably close to 0. :-)
