I think today everything is faster. The information amount you have to deal with daily is immense. And 5 years is a mega step in technology. 66 years like in your example is more than the business live of a human being. Of course, blockchain will be faster. And if the concept will not lead to the promised - it will disappeare as fast as it got a hype. But, this will not happen. Nobody needs the blockchain itself. But everybody knows that the digitalization and tokenizing of inter-company business processes is the future. The blockchain is one important concept to support this. By the way, good concepts are stable over decades. Most of the basic concepts of computer science have been the fundament of the digitalization for decades now. And these concepts are still unchanged and valid. For me, Blockchain is another fundamental concept.
