Itself, not natural, of course. But, it's patterns and interactions are a result of a natural system, us. So, like we have been able to notice similarities between small, natural system's growth and humans' population of the planet thru these large patterns we seem to follow. I would predict technology would still be subjected to these "natural" tendencies. My reference to the blockchain was in regards to how each block gets progressively more expensive to complete, correct? Just the way I understand up to this point. The encryption equations are getting ever more difficult requiring more computing power, therefore more energy per token. Hence the decrease in small time mining, because any single consumer device can't really make a dent in the problem. Again, speculating here based off my experiences thus far, and greatly appreciate someone with more, sharing theirs. Thank you.
