Key points
We are living in a growth period that isn't sustainable in a long run:
- If 2.3% increase of energy production go as usual in 2500 years we will need all the energy produced by stars in our galaxy
- If there is 2% growth of GDP, the economy is gonna double every 35 years. In 8200 years the economy would be 3*10^70 its current size. In our galaxy (a point we likely would not be able to travel beyond within the 8200-year time frame) there are likely fewer atoms than 10^70. In that case in 8200 years we would need to sustaining multiple economies as big as today's entire world economy per atom.
Main take aways is that it seems at some point we should hit either: collapse or stagnation.
