It becomes more difficult to specify what will happen in which decade or century the further we extrapolate out.

I can imagine consciousnesses in 'the cloud' could occur sooner than 200 years from now. Some things do just take time though even at peak development efficiency. The idea of practically building some massive energy transformer or engineering a planet is something that could take centuries.

I really don't think we'll ever have our flesh bodies travelling the stars like in Star Trek.
