I'm not a luddite (on hacker news lol) and I can clearly see the revolutionary potential of blockchain. But, for the love of God, can we STOP the blind short-term speculation on the promise of extreme wealth. Moderate investment can support development without the kind of hype that ruins lives and sullies public perception of the technology.
I first played around with blockchain in 2011 or so and I still don't know what actual utility this technology is supposed to have. I have never -- never -- encountered a value-producing use case for cryptocurrency that can't be solved by either signed git commits or a SQL database.
Around 2015 a lot of people I thought were smart enough were exploring use cases for blockchain. AFAICT everyone in that space either left the space altogether, is still rambling about solving supply chain fraud (...), or pivoted to shovel salesmanship to support speculators (or speculate themselves).
