> Urbit is a program

So what exactly makes it an OS? JVM is a virtual machine but we don't consider it an OS. So why not just call Urbit a virtual machine?

> What percentage of programmers even know how the internet works? A fair number of programmers have a decent sense for some corner of the modern computing world, but even seasoned professionals don't usually know the full structure of the digital world. How does BGP interact with the IP protocol? How do you make sure fsync() actually did what you wanted it to do? How does Linux overcommit_memory work? etc.

Seeing how Urbit runs on OS's such as Linux, uses TCP/IP for networking over the Internet, which itself relies on all those fun WAN protocols like BGP to make it work, it's not really solving those problems, just hiding it beneath another layer of complexity and terminology.
