As for the "singularity.." as far as it relates to computing (that is, the point at which artificial intelligence becomes self-aware), it is an inevitability. Moore's Law on processing power has held up for what? 30, 40, 50 years now?
I don't know see how curve-fitting a trend makes the leap to inevitability. How many thousands of trends lay in wrecked heaps by the roadside of history, trends that lasted more than just a mere few decades, trends that lasted for centuries and longer. People thought those much longer trends were inevitabilities, too. There has to be a much firmer arguement for this than simply, "it is, so it will always be." Isn't that one of the first attacks against peak oil, too? "We've always had oil, so we always will." I'm sure there's a nice word from a logic studies class that defines and refutes how faulty this line of thinking is.
To bring the discussion back around, I'd like to address this post.
This is a solid point, but it does not invalidate the theory, and the line of thinking is not faulty.
Your point would have been stronger still if you point out that accelerating technology is an exponential curve rather than a bell curve like peak oil.
Exponential curves pretty much always level off, the earlier scares regarding population explosions were based on an exponential curve in human reproduction, that soon levelled off and we have since found that people in developed countries have less children etc etc etc.
Normally, this is a crushing argument to any theory based on an exponential curve, applied to the Singularity you are talking about things like entire industries created and replaced in hours/minutes/seconds. ridiculous right?
The difference here is recursive self-improvement, and subjective time.
The argument goes, that once an AI is created, it will be able to design another AI that is better than itself, and so on. resulting in large leaps of improvement entirely out of our control.
Additionally, you may be familiar with 'clock speed' on computers? the speed of the processor, early super-computers took a long time to 'crunch' calculations that a desktop computer could do in an hour today. as processors get faster, they literally 'experience' the world faster. Your brain is a computer, and the rate that you perceive time going by is directly related to how fast your brain is running. If you had a faster brain, and were able to think twice as fast as you do now, you would literally experience time as going by slower. So the second part of the argument that addresses the exponential curve, is that the curve can remain exponential because each new generation will be experiencing the world and taking the next step faster, even though the same amount of 'thought' planning etc are put into it.
on a tangent of that argument it's also probably possible to create a computer simulation that runs infinitely (subjectively) even in a finite universe.
and as I said a bit ago, if the curve does level off, we are boned (and if it doesn't 'we' as in humans, are still possibly boned)
it's entirely possible that the curve will level off, it's also entirely possible (though unlikely) that oil will be smoothly replaced, that doesn't make Peak Oil uninteresting to consider or invalid.
