Well, I was just curious to hear it from the horse's mouth since they were answering questions in here. The answers are interesting, though I think they're answering a bit of a different question than I am personally asking.
Like, blockchain technology to power distributed ledgers for peer-to-peer payments is pretty interesting and I think I'd prefer it exists, consequences be damned. Stable coins don't really fit the same use cases though, and generally do have at least some reliance on a central party, so it raises the question whether the desired technical properties can't actually be achieved using traditional technology.
Unfortunately, the answers pretty clearly center around not what kind of technology is used to implement the ledger, but rather the choice to implement one versus using existing payment networks. I don't think this is done in bad faith, but rather is the result of very different perspectives.
I think the blockchain skeptics have a point: even if there is something especially technically advantageous about using the blockchain for this purpose that really couldn't be accomplished some other way, so far the only obvious incentive to do things this way appears to be regulatory differences in how the blockchain is regulated versus traditional ledgers.
Very tangential, but seeing major entities and even governments adopt blockchain technology has made me think a lot about potential consequences in the longer term. I really wonder what happens to the properties of various cryptocurrency networks when and if quantum computers scale big enough to start breaking our cryptographic systems. I guess CryptoNote is just toast.
