remember when blockchain hype was everywhere and people kept saying things like "oh I know it's so silly and overhyped but there will still be niche applications like tracking and securing supply chains"
and then it never fucking happened because the tech was crap and slow and expensive and error prone and difficult to manage and basically just worse than the existing solutions in every possible way
keep that in mind when people say "well it will have SOME good uses" about the tech fad du jour
