I think this is the right way to think about things, and that it answers Hal's question: "How can I judge an intelligence which is greater than my own?" The larger market framework judges new creatures by the supply of labor they offer, and the demand for products they embody. "Smarter" creatures are those that can command high rents/salaries for their labor.

In this framework, Vinge's singularity seems to be the idea that economic growth rates will be very high, because the marginal productivity of computer labor will be rising rapidly, because investments in improving such productivity will pay very large dividends. Even when most of the economy is devoted to developing better computer hardware and software, the marginal investment will quickly give back twice the "capital" invested. As usual, "capital" amounts are calibrated so that twice as much capital can produce twice as much stuff buyers demand for its own sake.

The sort of analysis in favor of singularity that I would find compelling would place this singularity claim in the context of what we know about the nature and history of the productivity of investments in computer hardware and software, or in the "software" of human mental abilities. Such an analysis would, in this context, identify specifically what is expected to change to make growth rates so much larger than recent experience, and show how such changes are likely to induce much larger growth rates.
