Blockchains exist for a reason completely other than performance. Of course a centralized database would perform better. That’s not the point. I think engineers keep getting hung up on this and don’t zoom out and see the big picture.
The parent article doesn't say anything about performance. Therefore this comment seems like a red herring. A case of not reading the article? The parent article's point is that most currently popular technologies found an application rather quickly, whereas blockchain technologies have been around for a long time (in tech terms) and still have not made ground.
Remember that blockchain technologies have become legal tender, have over a trillion in market cap, have become financial instruments traded by people around the globe, is taught at Universities and part of the CFA accounting exam, is in the news daily, has resulted in large investments in research, etc…
It’s impact has hardly been non-trivial. Just the impact on finance is substantial even if people seem to gloss over a new financial asset as “just finance stuff”.
