Good points. I think there are some proportionality issues, though. I would favor Ethereum over Bitcoin due to the strategy (proof of work concept and energy efficiency). There needs to be a physical currency component going forward, though. Cryptocurrency is all well and good if the world stops competing for supremacy of ideologies, but in the meantime, electronic systems are insecure and unreliable.

We have to take a step back from the whole videophone/entertainment/uselessness concept (look up how much of the bandwidth/energy is used for video on the internet, and how much is porn and redundant stupidity (people copying people copying people doing dumbass stunts, competitively posting videos of pirated videos, etc).

The human mind evolved to imagine and envision models of reality. It doesn't need video.

It's a pet peeve of mine because I worked on development of a 3D display invention for a while. The waste of resources trying to impress people who don't need to be impressed is unbelievable, when compared to 2D pictures and binary data.

As for the addiction to energy, it wouldn't be so bad if it was useful work that contributed to the future of places, but it's mostly just wasted or applied to destructive means for the mean Mean competitions.

That's really the problem: the direction of our efforts to extract instead of contribute.

No energy solution will fix that fundamental failing of our societal planning and function.

If humanity has free energy, it will just destroy everything faster.

Petroleum's problem was that it was so cheap. You can still buy 100 manhours of physical work for about 4 dollars, and it goes up in smoke for no useful purpose (as far as future people or Nature are concerned).

7 billion people only exist because petroleum feeds them and convinces them that their fantasies are more important than their physical places or their offspring.

Civilization (city-based isolation from nature) set up the evolutionary trap. Fossil fuels kept expanding it to capture more humans.

How do we re-train them to be useful to the planet before we let them out of the energy cost cage (fusion, solar, warp drive, Green Antarctica, etc)?
