Haven’t read through the whole thread, so it’s quite possible that all this has already been addressed:
[QUOTE=Simplicio]
Write down the most important technological innovations since 1900.
Now go look up the dates these items were first invented.
Really, do it. Its a pretty good exercise and only takes a few minutes.

The trouble with this thinking is that the time between invention and maturation of a technology is generally fairly long. Write down the most important technological innovations prior to the 1900’s and you’ll find that many of them were invented centuries or even millennium before. Generally, however, it took a great deal of time to refine those technologies to the level that they became truly important game changers for humans. During the period between when the technologies were invented and their development humans didn’t just sit around doing nothing…the maturation of the technologies themselves spurred on technological development.
Take, for example, gun powder. One of the biggest game changing technologies and invented well over a thousand years ago. It took centuries of development and change before it became useful as a tool both on and off the battlefield. During that period, it was constantly (though fitfully) developed and refined, and through that process it sparked multiple other branches of technological development, which sparked others, etc etc.
Now, take something like the Air Plane. From invention to useful to mature took less than a hundred years (granted, we continue to refine the technology even today). The pace of technological development is speeding up.
Ok…take the internet. This time, the pace from invention to useful to mature tech is less than 2 decades (again, we continue to refine it). The point here is that the pace of innovation is speeding up, and, of course, that these inventions are sparking new innovation and technological development both in parallel and in new directions.
So, to answer the OP, why would we not reach a technological singularity? The only reason I can think of is that we manage to wipe ourselves out first. Resources? I don’t think that will be a particular problem, to be honest. There are plenty of untapped energy resources right here on earth, let alone in our solar system…practically unlimited resources in that direction, in fact. That we won’t be smart enough, somehow? I highly doubt it. I think that technology and innovation are converging with science to tackle some of the last really big mysteries out there, and while I don’t think we’ll ever know everything, or that the journey of discovery will ever be done, I think that we won’t hit some kind of metaphysical brick wall that we can’t get around (always assuming we don’t wipe each other out, or get wiped out by our planet or by a really big rock).
