That's exactly what you're complaining about.

Who is complaining?
Don't misread my tone. I am sincere but I am not upset - quite the opposite. Amusement is my current theme.

unmitigated glitter farts.

Best thing I have ever heard of. Better than baby butts and the baby powder bomb cloud.

You start expecting that the universe will justify your optimism.

The universe DOES justify my optimism every second of the day. Even on shitty days.

We've had holy electronic currencies being traded openly for quite a while before "blockchain" became the new tulip.

Cryptos maybe tulip-like in patterns but blockchain is nothing close to the tulip.
I hope you have read this one: http://cryptocoremedia.com/tulip-mania-vs-bitcoin/

Again, maybe it is simply ignorance of history that leads people involved in cryptocurrencies to believe that they are somehow notionally special and engaged in a technology that "will improve the planet."

I hold blockchain technology in a special pedestal yes. Not cryptocurrency. I KNOW blockchain improves life- I encourage you to read this one too. : https://cryptocoremedia.com/blockchain-humanity/
remember I am not saying this is what will come to be I am saying this COULD be. If humans could see past the decade they live in.

So it's not possible that "the way that works" doesn't anymore. There's no evidence for that, we don't see that, and it's silly to suggest it.

It maybe rude of me to have put it that way. I rephrase.
"The way things work" will be continuously improving thanks to the next round of humans and yes, thanks to blockchain technology. ( not cryptocurrency)
Read the article linked above pretty please. Thanks
Things still work as usual... but not in a way that is most beneficial for our species. That is a fact.
