I'm afraid I don't have any project to put on your list. My biggest hope is around MNT reform putting a RISC-V module in their laptop sometime in the next 5 years. Or maybe some other project builds a laptop around a successor of

The word "crucial" here implies (to me) that it's almost impossible for the distribution to become less concentrated if there is no dilution. So you think that flattening of the distribution of Bitcoin is (almost) impossible?

Agree. Heat pumps are likely the most efficient way to heat/cool something we'll ever have. But that's besides the point. The question was whether mining is becoming more efficient, not whether mining can deliver secondary pu

Societies' gains as an effect of this specialisation is just one (albeit an important one) aspect of the whole optimisation. Anti-fragility and redundancy typically decrease the number of (costly) disruptions in a system and thus the p

Developments such as passive heating homes that reduce energy consumption to almost zero, might solve these problems. But that'll take another 30 years at least.
