The third option.
There are a few paths our world can go down. I used to believe that there were mutually exclusive options of destroying ourselves or enjoying the benefits of the technological singularity.
But there might be a third option, we could drain all the worlds important resources leaving nothing for distant generations to come.
Society might regress into a pre-iron ore era. Where the only tools we can make are those using the most common of materials.
I doubt it will happen, but it is interesting to think about.
