You misunderstand me, I agree, just trying to generate discussion. I think the grey goo consuming the universe is the horrible hellish end result of infinite growth and a good argument that at some point moderation, priorities, and a "good enough" need to be declared. Also maybe thinking instead of growth about transformation, that innovation and newness doesn't always have to mean ever increasing consumption. What "blocks" could be exchanged for other new and interesting "blocks" instead possibly. How could the blocks be better arranged?
