It's not a brand new technology, it's 12 years old. Back in 2008, the iPhone was new technology -- look at it now. Bitcoin remains unchanged, as does the fundamental technology underlying substantially any relevant cryptocurrency. Proponents need to get over this whole "it's new" business. It's not new. It's
old. Can you think of any other piece of software or hardware you continue to use from 2008 that you consider "new technology?" Do you consider the original iPhone (2G) to be "new technology?"
I don't think anyone was disappointed with where the Internet was in the early 80s and 90s, and that's because it fundamentally opened up new avenues for people to express themselves, new ways to interact. It wasn't perfect, but it created something new nobody had before. Many things!
The ability to move money online has been with us for decades. It's not new, either. Crypto doesn't open up any new capabilities except harder-to-track ransomware payments.
