How can a technology that solved the Byzantine fault tolerance problem be a fraud (https://en.wikipedia.org/wiki/Byzantine_fault_tolerance)? The problem was described by a Microsoft engineers in 1982 (https://www.microsoft.com/en-us/research/wp-content/uploads/2016/12/The-Byzantine-Generals-Problem.pdf ) and until Satoshi, no other solution worked. It sounds like the inventors should receive a Nobel prize, not be accused of fraud.
This new technology allows us to write and deploy autonomous systems that eliminate the need for middle or central authorities, costly system/security administrators, distributes infrastructure costs and is programmable. With all these improvements, do you really think Bitcoin will fail? Usually technologically advanced systems displace the old technology but it takes time and the incumbents aren't too happy. Think of the horse and buggy. Some doubted the automobile and Ford's "crazy" assemble line had a chance to compete.
