That is a good point that if attain mass adoption, most users won’t even realize they are using a blockchain.
I mean when there exists desirable things they can’t do with fiat. For example, earning tokens from writing and commenting. Beyond that is for example displacing all the centralized databases on the Internet, smart contracts, distributed microeconomies/micronations, decentralized speculation, new forms of gamification and monetization of Internet and computer activities, etc..
As I wrote at the bottom of my blog, I read Szabo’s Bitgold in early 2009 after writing something somewhat analogous 14 days before he published:
P.S. I stumbled onto an essay I wrote in 2008 contemplating something like Bitgold or Bitcoin and published 14 days before Szabo did. I had not worked out how to eliminate the physical backing entirely, but I was spot on the concepts of cryptography and decentralization.
I heard about Bitcoin sometime after that (perhaps it was 2010), but I was distracted on other life matters. Risto Pietila and I were dealing in physical silver from 2008 to 2009 (we had met on Jason Hommel’s forum). In 2012, he asked me about getting into Bitcoin but I told him I was preoccupied with my illness (which was acute hospitalization in May). In early 2013, he asked whether he should sell $100,000 of silver and buy BTC at $10 and I said yes. I wasn’t able to join him because I had lost $75,000 of fiat in 2012 (side-effect of the flight or fight effect of my illness) and “theft” of my silver and gold over the years. From 2013 to present, I became expert on blockchain technology, having been a computer programmer since age 13 (age 52 now).
