The technological case against Bitcoin and blockchain

Bottom line: Blockchain is mostly a solution looking for a problem. And I say "mostly" just to leave the door open to problem spaces that have yet to be fully explored.

Blockchain technology is a train wreck. For its intended purpose, it's beyond useless — an unbelievably inefficient non-solution whose most impressive features are things we don’t want, that also gives us huge downgrades in every aspect that we do care about.
