Quite brilliant unbiased appraisal by Rick Falkvinge, of how the Crypto 'holder of value / payment' blockchains, may evolve. This the highlight for me, from the interviewee:
"We were there with streaming video for 10 years before YouTube hit in 2006. We were there with blogging for 10 years before WordPress and Typepad hit. We were there for about 10 years with file sharing before Napster hit in 1999. These things take about 10 years before somebody hits the right usability key. And remember, this is a technology that was devised in 2009. It’s possible that, if we’re looking at a possible mainstream breakthrough around 2019, ten years from then, then the company which will make this breakthrough has not been even founded yet."
