that has nothing to do with your argument about running out of etherium as "fuel". That's silly.
You sure have a very overactive imagination. Where exactly did i write we will "run out of ethereum as fuel"? Seems to me, perhaps; your brain is running out of oxygen since it's starting to hallucinate? Hallucinations are a well-known side-effect of lack of oxygen. Your brain must be hallucinating, since I never ever wrote anything about running out of ethereum as "fuel". Thus, one should then conclude you should perhaps try breathe a bit more often?
