For a number of technical reasons (security and scaling) I've come to believe that urbit or something much like it is inevitable.
IPv6 might solve the address space problem but the high level problems (e.g. constant privacy invasions) are such a clusterfuck that it is crippling IoT and other potential growth sources.
I'm happy to shill for them because there really aren't that many people doing truly new things with computation in Silicon Valley.
