For a start, the entire series of responses in this article is nonsense, beginning with the very first claim about "Web 3" somehow being a response to twitter changing their API. There's nothing about blockchains that stop companies from changing or shutting down an API. Chris even appears to agree with this in a later response!
Up to now everything about "crypto" has just been a vehicle for speculation and get rich quick. There is no real world problem being solved. I have seen many possible uses proposed but none actually enacted and every case were blockchain may be used, something far more practical is already in place solving that problem and doing so without the impact to the environment or the electronics market.
