Yeah and look at how much things have changed since then... Why throw the entire concept of creating a digital currency/ledger? Why be so against it at the core? It's one thing to be against Bitcoin, or proof-of-work, or literally any other current method of digital currency, but why dismiss the concept outright as some kind of old-timey dog & pony show who will be another lesson we learn the hard way?
Sounds like Luddite thinking to me. Sounds like fear of new technology.
How many literally countless attempts at human flight were there, many that were awful, stupid ideas, before we finally figured out the best way to do it?
Or maybe we should have just given up on the idea of air travel altogether...
