I’m wondering if the technological innovation of the human race as reached a long term lower slop of a plateau. I remember discussions that Moore’s law (a thesis about computing power) would never be violated and that’s come to pass.
The one major development that may make things continue on a path of social development based on increasing per capita energy expenditure would be effective fusion technology, which seems feasibly on the long term (ie 2050+) horizon.
Other than that I think that most advances would appear to be incremental with advances in materials and computing being more a matter of degrees than really effecting social structure.
