This also shows a painful ignorance of history.<br>
<br>
Back in the day there were implementations of network protocols that<br>
carefully implemented each layer separately with clearly defined<br>
interfaces between each. They all shared the characteristic of being<br>
stupendously unusably slow, and in many cases impossible to debug<br>
because all of the interfaces offered an exponential explosion of ways<br>
to screw up.<br>
<br>
The pragmatists that built the Internet defined interfaces where they<br>
were useful and didn't obsess about places where they weren't. There<br>
were a lot of experiments some of which succeeded (most of Berkely sockets)<br>
and some of which didn't (the Ethernet trailing header hack.)<br>
<br>
Unfortunately, most of the people with that experience are close to<br>
Steve's age, and there aren't a lot of them left to remind us of why<br>
our networks work the way they do.<br></blockquote><div><br></div><div>That makes it very important for the Internet Society to ask Steve, Vint and others to document in greater detail, with documentation assistance provided on the scale of a Book Publisher, how the Internet was built, the difference between Internet and the Web, the difference between Internet and Google (to help us understand that the Internet is not Google + Instagram + Whatsapp), what are layers, how layers are sacred, how layers are politically and commercially messed up, and why it is important to make the Network work the way it should. Their work is much more than that of imparting this understanding, but in this context, it is one of the top most items in a To Do list.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
