You're proving my point here right? The trust and security of the Bitcoin blockchain does not have value to you, so in your mind we're completely wasting all that energy. The fact is that a lot of "useless" things cost a lot of energy - Facebook? Useless to some, not to others.

Personally I view Bitcoin as the first implementation, we can and should improve on that concept. See Polkadot, Algorand, Eth 2.0 etc. as the new generation which does not use up a lot of energy.
