"All exponential growth comes to an end eventually." Perhaps. But it may be that this limit is very far in the future. Technological progress relies on matter to store information and to built tools, and energy to apply those tools to accumulate information. There is a lot of matter and energy in the Universe, so much so that even were we to continue at our current rate of progress, we wouldn't hit these known physical limits for a considerable span of time. There may, of course, be more subtle limits we are currently unaware of, but I'm inclined to believe that technological progress will continue at an accelerating rate for a very long span of time.
