A chair's proof of concept doesn't burn the energy of a small industrialized nation?

Computers as a whole burn the energy of many small industrialized nations. Is that to say computers shouldn't be used? Or is it simply a statement of how widely used computers are?

you need to take the cost/benefit. Computers may use a lot of energy but they're essentially the nervous system of collective humanity now - they're eminently useful. Cryptocurrencies on the other hand - their primary utility is taking person A's money and giving it to person B without producing any beneficial side effects.

Nuclear energy vs nuclear bombs? How you use it makes a difference?

The position of web3 is that we should be using "chairs" to run websites.

The infrastructure of crypto is blatantly inappropriate for the domains people are trying to apply it to. Which leaves open the question, why are they pushing for it?

The answer should be clear to anyone with a passing knowledge of the crypto scene.

Is this the position of crypto or the position of people driving crypto? I am trying to understand here if there something inherently wrong with the technology or just with the people running it.
