These have apparently fallen into your backlog, but they were timely when sent. If you consider them still timely, how about adding a brief preface to the effect that they concern ------- Forwarded Messages To: farber () cis upenn edu Cc: willis () rand org Reply-To: willis () rand org Subject: Re: IP: More on Breaking the Tech Myths (before they break us) In-reply-to: Your message of Mon, 07 Dec 98 06:56:17 EST. <4.1.19981207065552.03c687b0 () linc cis upenn edu> Date: Mon, 07 Dec 98 09:23:09 PST From: "Willis H. Ware" <willis () conrad rand org> - -- Folder: YES - -- Dave: Danny Cohen's recitation of facts and dates is accurate. The Baran work (done in the early 60s) was documented in a series of 12 research memorandum all of which are now on the Rand external Web page under "Classics" (http://www.rand.org). Indeed this work was used by ARPA to persuade DoD and others to invest in packet technology and all that came along with it. All of this history is well documented and cited in various places with proper credits. At one point, Larry Roberts commented to me personally: "..please come to Washington and help us make people understand how we're going to change the world." That is an accurate verbatim quote. Just a little point in passing (also well documented). Paul Baran used the phrase "distributed communications" in his writings. The phrase "packet switching" was originated by Donald Davies who came along with the concept soon after Baran's work was published. It is not clear to my knowledge whether Davies had knowledge of Baran's work, especially since one of the original series of documents was classified.

Ware" <willis () conrad rand org> - -- Folder: YES - -- Dave: After replying to Danny Cohen's message, I went back and read the original mythology discussion. A few more observations ... 1. The genesis of the Baran work was a concern by the USAF about survival of command-control during a nuclear war. The USAF leadership expressed this concern to Frank Collbohm, president of Rand at the time, and he relayed it to Keith Uncapher, Paul Baran and others. I'm a little hazy about who carried the message from the USAF but it might have been Curtis LeMay. Among other views, it was thought possible to exploit the AM network which was widespread and with numerous nodes (stations) even in the 60s. I well remember a variety of discussions between Paul, AT&T leadership, and others about the coming transition from an analog world to a digital world. It was a hard sell, and except for ARPA's infusion of leadership and funds, the digital networks of today could have been much slower in arriving. 2. In regard to the following:
This myth has served to help us rationalize constant expenditures on new computers and upgrades. But while a 300mhz computer costs less today than a 200mhz model did a year ago, we spend more total cash if we continually replace our machines for little or no added benefits. In a flourish of planned obsolescence bravado, computer companies and software writers create chips that require more advanced operating systems, and operating systems that require newer chips and more memory. Buying more computers, even if progressively cheaper, costs more.
There is nothing new about that statement. In the days during which IBM (and others') "big iron" (mainframes) were dominant, one of the inside jokes and truisms was that: a. With every new introduction of a machine, you would wind up spending the same amount of money; and b. The increased performance was inevitably diluted by the new and more demanding system-level software. And in the same vein:
Otherwise known as Moore's Law, the myth is true when taken in isolation.
Moore's law (although I'm not certain when the name was attached to it) was around long before Microsoft became the powerful corporation that it is. The author was careless about the facts of history. What goes around comes around ... it's hard to understand where this author is coming from. Willis Ware ------- End of Forwarded Messages
