The events described here took place in 2016, over six years ago. That's a long time in technology!
Since then additional billions of investment dollars have flowed into the space (a "VC crypto spasm" as the author calls it). Yet zero meaningful products have emerged.

How long will this have to go on? There are real things to build in software. This nonsense is both an embarrassment to the profession as well as a giant distraction. Time spent thinking about cryptocurrency mindgames is time you'll never get back to use on something productive.
