Robin, perhaps you could elaborate a little bit... assuming I understand what's going on (I'm always hopeful), the "recursion" here is the introduction of output being a function of "subjective time" (y) instead of "clock time" (t), and, further, y -- it is postulated -- is related to t by:

dy/dt = e^y

because the ratio of y to t is directly related to output (which as noted above is said to be an exponential function of y due Moore's law-type arguments).

That's seriously "strange". It is very different than a non-"recursive" analysis where, say, dy/dt = e^t. I could imagine you objecting to the veracity of this model, or claiming that this type of recursive loop is standard practice. Which of these are you saying, or are you saying something different entirely?
