Yes, that's true. For example, sometimes things suffer a catastrophic collapse. Other times, they may just slowly fade into irrelevancy.

Sometimes they reach an equilibrium and stabilize.
For bitcoin, I think the energy consumption will level off as the block reward declines, with the block reward eventually going to zero. The miners are then paid by transaction fees only. Only the most efficient miners will survive in this environment and these factors will ultimately limit the energy consumption. The projections of this author are stupid.
Bitcoin is a better money, whether people want to admit this or not or realize this or not. People won’t have a choice in the matter, just like gold displaced seashells and notched sticks as money. The market will force bitcoin on people. It won’t happen right away. It will take awhile. But it will happen.
