This energy consumption narrative is garbage.  It is not better technology to not have PoW.  Mining crypto uses like 1/15th of the energy involved with gold mining alone.  Let alone gold transportation or other things involved with the just Gold.

Most of these top non minable coins got their valuation mainly through a completely overhyped ICO in a mania.  ICO have mostly been BS non functional vaporware scams and PoW mostly functional.

There is a frustrating lack of common sense in crypto, and it leads to people not doing research on their own and regurgitating crap.

Gpu mining at home might not last if it gets industrialized,  but crypto should resist that to keep decentralization and censorship resistance.  That which is the only reason crypto is what it is....
