A society may grow spatially and fill the volume of its solar system with habitats, build a Niven ring or Dyson Sphere, may settle nearby stars, and develop human equivalent artificial intelligence, yet not NEED to develop computers beyond one or two magnitudes of human IQ. Technological advancement is not a goal in and of itself, it merely serves to optimize human existence, and it does so at economically cost effective rates. Dyson's major error in his calcuations was to assume no increase in efficiency of utilization, which is not only crucial to make further growth cost effective, but establishes resource re-utilization at rates of greater efficiency as a cost effective strategy, eventually concluding in a species being able to utilize resources at more and more efficient rates.
Since our population growth rate is already at around 1%, if we increase the education and intelligence of the population more, the growth rate will fall even faster, possibly into the negative percentages much like european countries (which is why they can sustain lower economic growth rates and maintain standards of living with the US). As longevity increases in a population, the desire to reproduce decreases, thus reducing the necessary economic growth rates to maintain improving standards of living.

Comparing the behavior of non-intelligent species to the long term behavior of intelligent species if fallacious and fraudulent.

And it is yet to be proven that some or all 'exponential growth paths' are not paths of the third order, maxing out at some plateau, the highest being that of light speed.

Since greater intelligence and education result in lower population growth rates, its not hard to imagine a future where the population falls down to the levels of the previous hunter gatherer society (about 2 million per planet), yet each individual is of high intelligence, and engages in much intellectual interaction outside of the feral/agronomist lifestyle.

Moore's Law has yet to be shown to have no upper limit. Better yet, light speed itself puts a limit on maximum growth of computational technology. Making Moore's Law a Holy Mantra is an error of faith. Not very scientific.

Your error is to assume that it will happen sooner rather than later. Much the same errors the early christians made in expecting the 2nd coming in their lifetimes. Sounds to much like a religious attitude to me.

Evolution is a result of pressures against the survival of the individual. Once the individual is practially immortal and intelligent enough to handle most eventualities in the physical world, they have no further need of evolution.

Your points here illustrate the proof of my statement. You refuse to acknowledge that once some part of the population 'transcends' (quotes being to denote your mystical attitude toward that condition), that the remaining population will not automatically be transcended or be destroyed. That we have stone age cultures in coexistence with our own right now illustrates the fallacy of your argument. Your argument assumes a level of evil and callousness in the motives of transcended beings that I personally would take as an argument to stamp out all efforts to transcend.

You fallaciously assume that an AI will not develop a moral code, as if there is no objective morality. Sorry, null program.

Read it. You still are evading the point. Just as there are stone age cultures alive and functioning today, 20th century cultures will survive into and beyond the time of any supposed date of 'singularity'. You need to stop looking at it as some sort of Day of Rapture that all will participate in or go to hell.

If you do so and do not accept any objective morality of survival and coexistence, then I will be sure to nuke you before you attain your goal. Kapisch?
