It's like saying we're going to suffocate right now because all the oxygen molecules will run away a mile away. Possible, but too little of probability.
You are a gibberish merchant. Turning of computers that are no longer required are are merely costing electricity is normal procedure. Your oxygen analogy is loony.
People will NEVER lose interest in a trustless ledger, because it is impossible having 100% citizens who trust banks and govts and feel free with giant fees while sending money abroad. My oxygen analogy is not so crazy, there was some deathes like this under certain circumstances.
> People will NEVER lose interest in a trustless ledger
Not even wrong. Most people never had interest in it in the first place. And even among those who do, it's of no utility in and of itself, only in what it can or can't enable. They will lose interest when the answer is "nothing".
I mean, you sound like a religious preacher. It's sad.
