How do you measure the "explosiveness" of an explosion? By measuring the base of its exponential growth? If so, I would classify the hypothesis that the explosion will get "more explosive" as a somewhat speculative one. The growth in CPU clock rates has already run out of steam. The explosion may well get faster in some areas - but getting more "explosive" has got to be different from that.

Today, information technology is exploding in the same sense that the nucleii in a nuclear bomb are exploding - by exhibiting exponential growth processes. The explosion is already happening. How fast it is happening is really another issue.
