From Cryptocurrency is an abject disaster by Drew DeVault:

Cryptocurrency is one of the worst inventions of the 21st century. I am ashamed to share an industry with this exploitative grift. It has failed to be a useful currency, invented a new class of internet abuse, further enriched the rich, wasted staggering amounts of electricity, hastened climate change, ruined hundreds of otherwise promising projects, provided a climate for hundreds of scams to flourish, created shortages and price hikes for consumer hardware, and injected perverse incentives into technology everywhere.

  • takeaway n°1: even being super knowledgeable about this space doesn’t shield you from those tricky schemes. So what about the average Joes and Janes?
  • takeaway n°2: Ethereum-adjacent discourse is straight up alien speak to me. Even though I generally feel rather proficient on the intellectual level, I’m still dumbfounded when I read the kind of mumble-jumble this thread is riped with. And in a very different way than when I’m reading something technical in a field I am not acquainted with, like say particle physics or philology.
