Blockchain is quite old at this point by technology standards, no? In 2017 there was a ton of attention and funding going into the space - it's not as if there hasn't been the opportunity to do something interesting with blockchain.
The fine article and your comment both say crypto is 'old' tech. TFA points to iPhone's 2007 release date as if no one (even apple themselves had tried to crack the personal digital assistant before). Which is a laughable omission of history. The first PDA landed in the 80s. Apple started development in 87 on the newton and didn't have a product til 93. The iphone stands on the ashes of 2 decades of product and engin…
But I don't totally understand your comparison of early PDA's to the current state of cryptocurrency. Palm pilots were a successful product in their day. Blackberries were hugely successful. It's not as if the iPhone was the first example of value being created in this space.
As far as blockchain, from what I can tell, the only value its creating so far is for drug dealers, those executing ransomware attacks, and people running cryptocurrency exchanges.
I'm not ruling out the idea that someone will find an interesting use-case for cryptocurrency in the future. But what seems a bit strange to me is that cryptocurrency advocates seem to want us all to give a ton of attention and investment towards this space which so far has produced nothing of value. It seems to me that the rational standpoint will be to ignore it until someone can actually demonstrate the "potential" which has been promised for so many years now.
