Lack of cheap energy.
Ecological disruption.
Diminishing returns of computation.
Diminishing returns of engineering.
Inability to precisely manipulate matter below certain size thresholds.
All sorts of ‘boring’ engineering issues by which things that get more and more complicated get harder and harder faster than their benefits increase.
