Definitely a fun read, lots of things to nod and shake your head at. For example if we've mastered the fusion power generation process then rather than carbon remediation we may find we have to burn things occasionally to boost atmospheric CO2, the reasoning goes that we've basically converted all of the arable surface area to 'farm' land, we have converted all of our industrial and motive mechanisms (cars/trucks/trains) to electricity, we use the Fischer-Tropch process to create jet fuel which can take CO2 out of the air, so not only are anthropogenic sources of CO2 but natural sources (forest fires) are removed from the system. If we are pulling energy geothermally out of volcanic hot spots that will leave their tops just frozen enough to not erupt (another giant source of atmospheric CO2).

It is really really hard to predict past a point where the energy problem becomes 'solved.'

I also expect that all of our computing / electronics devices will be essentially 3D printed out of carbon in various forms (tubes, balls, graphene) providing the various roles of switch, conductor, gate, and substrate. Those will be connected by a mesh of networking that is a couple of gigabits wireless and perhaps a terabit when hard connected. The low marginal cost of bandwidth will make it pretty much non-blocking bandwidth everywhere.

I expect we'll be eating a manufactured food product that is tasty and nutritious and the domestication of livestock and the use of any other living organism (including plants) will be considered 'quaint'. No one will have to go hungry because the combination of low cost energy and the ability to assemble food will allow for free 'food' (although not designer, "high end" food).

I think the more interesting question though comes from biology, which is to say if we have completely decoded cellular biology then there won't be any excuse for being sick or not 'healthy' (and by that I mean optimal function of all organs including the brain). At some point during the development of that capability the aspects of ones genetics which determines sexual orientation will be completely mapped out and understood and there will be a big debate about what we do about that, do we 'cure' homosexuality, do we offer to make everyone 'omnisexual' etc. There will be huge and heated debates about what is and what isn't normal.
