It's not an argument, it's people pushing random bullshit onto clueless consumers who lap it up.
It's been this way since always. Even tech-literate people fall into traps propagated by the 'current hype' scammers. Even in software development people keep rediscovering the same solutions over and over again, repackaged like 'Wow look at this super cool new thing'.
Most problems today aren't technical. Technology will not be able to solve them, and many problems will be made much worse with new technologies because of how this society is set up.
So crypto (and all its ilk) will not in any way change the world. It will only keep it as it was set up.
Nah I just have completely lost interest in this conversation. You have convinced yourself that crypto sucks. I can't change your mind. Go do something productive with your day.
