i should be smarter than to argue with bitcoin maximalists about the energy intensity of bitcoin, but seriously, technologists, the industry has a problem with energy usage *even at this scale*. if it 'actually' scaled to replace everything it would be catastrophic.
i’ve been concerned about this since 2011 but back then was even more concerned about whether 51% attacks would materialize, since the economic incentive might not be enough if either you could double spend and get away with it, or short bitcoin (somehow) & compromise the network

There are balance issues when the same hardware can (efficiently) mine multiple currencies. Because mining difficulty is estimated based on past block times (in most CCs), and because mining rounds are discrete, it isn't even clear that there is a stable incentive.

That is, switching back and forth rapidly between CCs could become incentivized. Not ideal for the *users* of the CC, since they would see completely erratic block times, but great for the miners.
