Brian Kernighan on the origins of Unix

And even if it technically worked, I don't think it would provide decentralised control in any meaningful sense. You need an organisation to design the protocol and to update it over the years (to fix security/performance/legal problems with the original design, and to continually improve security/performance/features/etc to keep up with the proprietary competition), and a small enough number of organisations building the hardware and implementing the software so that there's a reasonable chance of interoperability between them all. I don't see any practical way to design a network where users aren't expected to put trust in and give power to someone else.
