While I was working at One Laptop per Child, I noticed a small, birdlike man perched over my shoulder looking at my two screens. Hmmm he looks familiar from one of my books maybe, oh shit, it’s Marvin Minsky!
Henry, what are you doing?
!He knows my name!
This to me was roughly the equivalent of being a fair to middling painter tending to your business and suddenly Leonardo da Vinci shows up and is asking you what are you doing, by name.
SO I explained well I am doing this that and the other thing and then I said you know Marvin, 90% of what I am doing is repetitive in nature and goes in through standard in and out through standard out. When can I have an AI that can do this 90% of the work for me?
And without pausing he said. “Five years.”
We both busted out laughing.
The same answer, I suppose, he had been giving since 1959, when he co-founded the predecessor of CSAIL, the year he became an MIT Professor and the year I was born.
I also had a long conversation with him in another instance about how AI needed to use the basic story structures of folklore in order to construct narratives about events that humans would remember and regard as credible and later I gave him a copy of Propp’s Morphology of the Folktale.
A great mind, an excellent listener and a lovely gentleman.

Seems everyone is lionizing Aaron Swartz. Aaron is someone I was acquainted with peripherally through mutual friends at One Laptop. He was, and remains, my friend on Facebook. I have to say aaronsw is not my hero.
If I thought it was justified to take all the documents in JSTOR I would have done when I was the sysadmin for the company that wrote the first interface to it. I don’t and I didn’t. I never even looked at a single document and I had root on everything.
Same is true for the American Mathematical Society and about a million of their documents I worked on the public interface for back in the 80’s. Never looked at a one.
Aaron was very charismatic, brilliant, and had a lot of good ideas. But he also according to what has come out, acted incredibly stupidly in the whole scenario with JSTOR and MIT. They kept blocking him and he kept coming back. Hello, clue?
But maybe he thought of this as civil disobedience and in some sense meant to get caught. If so I think he totally wimped out rather than doing the six months they offered him or going to trial and potentially taking a draconian sentence.
Not to say I think he was treated fairly. Given that JSTOR and MIT saw no reason to prosecute (or that’s the official story at MIT now anyway), and that there is apparently no evidence that documents were ever exfiltrated off-site or published if I was the prosecutor I would have exercised discretion and taken a pass on this one. No harm, no foul.
It worries me that Aaron is being made out to be a hero who deserves to be be emulated. He wasn’t, and he doesn’t.

From 1969 to 2013, the Internet has gone from this:
I’m going to talk about some of the people who I think were important in setting the shape of things to come. My criteria isn’t really who is most worthy but rather, who did really important things, is interesting, and some early figures have a local Boston connection as you will see.

As We May Think:
“The camera hound of the future wears on his forehead a lump a little larger than a walnut. It takes pictures 3 millimeters square, later to be projected or enlarged, which after all involves only a factor of 10 beyond present practice…
The Encyclopoedia Britannica could be reduced to the volume of a matchbox. A library of a million volumes could be compressed into one end of a desk. If the human race has produced since the invention of movable type a total record, in the form of magazines, newspapers, books, tracts, advertising blurbs, correspondence, having a volume corresponding to a billion books, the whole affair, assembled and compressed, could be lugged off in a moving van. Mere compression, of course, is not enough; one needs not only to make and store a record but also to be able to consult it, and this aspect of the matter comes later. Even the modern great library is not generally consulted; it is nibbled by a few…
All this is conventional, except for the projection forward of present-day mechanisms and gadgetry. It affords an immediate step, however, to associative indexing, the basic idea of which is a provision whereby any item may be caused at will to select immediately and automatically another. This is the essential feature of the memex. The process of tying two items together is the important thing…
Wholly new forms of encyclopedias will appear, ready-made with a mesh of associative trails running through them, ready to be dropped into the memex and there amplified. The lawyer has at his touch the associated opinions and decisions of his whole experience, and of the experience of friends and authorities. The patent attorney has on call the millions of issued patents, with familiar trails to every point of his client’s interest. The physician, puzzled by its patient’s reactions, strikes the trail established in studying an earlier similar case, and runs rapidly through analogous case histories, with side references to the classics for the pertinent anatomy and histology. The chemist, struggling with the synthesis of an organic compound, has all the chemical literature before him in his laboratory, with trails following the analogies of compounds, and side trails to their physical and chemical behavior…
The historian, with a vast chronological account of a people, parallels it with a skip trail which stops only at the salient items, and can follow at any time contemporary trails which lead him all over civilization at a particular epoch. There is a new profession of trail blazers, those who find delight in the task of establishing useful trails through the enormous mass of the common record. The inheritance from the master becomes, not only his additions to the world’s record, but for his disciples the entire scaffolding by which they were erected…
The impulses which flow in the arm nerves of a typist convey to her fingers the translated information which reaches her eye or ear, in order that the fingers may be caused to strike the proper keys. Might not these currents be intercepted, either in the original form in which information is conveyed to the brain, or in the marvelously metamorphosed form in which they then proceed to the hand?
In the outside world, all forms of intelligence, whether of sound or sight, have been reduced to the form of varying currents in an electric circuit in order that they may be transmitted. Inside the human frame exactly the same sort of process occurs. Must we always transform to mechanical movements in order to proceed from one electrical phenomenon to another? It is a suggestive thought, but it hardly warrants prediction without losing touch with reality and immediateness…”

Memos to the Intergalactic Computer Network
“In the foregoing, I must have exercised several network features. I engaged in information retrieval through some kind of system that looked for programs to meet certain requirements I had in mind. Presumably, this was a system based upon descriptors, or reasonable facsimiles thereof, and not in the near future, upon computer appreciation of natural language. However, it would be pleasant to use some of the capabilities of avant-garde linguistics. In using the borrowed programs, I effected some linkages between my programs and the borrowed ones. Hopefully, I did this without much effort–hopefully, the linkages were set up–or the basis for making them was set up–when the programs were brought into the part of the stytem [sic.] that I was using. I did not borrow any data, but that was only because I was working on experimental data of my own. If I had been trying to test some kind of a theory, I would have wanted to borrow data as well as programs.
When the computer operated the programs for me, I suppose that the activity took place in the computer at SDC, which is where we have been assuming I was. However, I would just as soon leave that on the level of inference. With a sophisticated network-control system, I would not decide whether to send the data and have them worked on by programs somewhere else, or bring in programs and have them work on my data. I have no great objection to making that decision, for a while at any rate, but, in principle, it seems better for the computer, or the network, somehow, to do that. At the end of my work, I filed some things away, and tried to do it in such a way that they would be useful to others. That called into play, presumably, some kind of a convention-monitoring system that, in its early stages, must almost surely involve a human criterian as well as maching [sic.] processing.”

“The earliest ideas for a computer network intended to allow general communications among computer users were formulated by computer scientist J. C. R. Licklider of Bolt, Beranek and Newman (BBN), in April 1963, in memoranda discussing his concept for an “Intergalactic Computer Network”. Those ideas contained almost everything that composes the contemporary Internet. In October 1963, Licklider was appointed head of the Behavioral Sciences and Command and Control programs at the Defense Department’s Advanced Research Projects Agency — ARPA (the initial ARPANET acronym). He then convinced Ivan Sutherland and Bob Taylor that this computer network concept was very important and merited development, although Licklider left ARPA before any contracts were let that worked on this concept.
Ivan Sutherland and Bob Taylor continued their interest in creating such a computer communications network, in part, to allow ARPA-sponsored researchers at various corporate and academic locales to put to use the computers ARPA was providing them, and, in part, to make new software and other computer science results quickly and widely available. In his office, Taylor had three computer terminals, each connected to separate computers, which ARPA was funding: the first, for the System Development Corporation (SDC) Q-32, in Santa Monica; the second, for Project Genie, at the University of California, Berkeley; and the third, for Multics, at MIT. Taylor recalls the circumstance: “For each of these three terminals, I had three different sets of user commands. So, if I was talking online with someone at S.D.C., and I wanted to talk to someone I knew at Berkeley, or M.I.T., about this, I had to get up from the S.D.C. terminal, go over and log into the other terminal and get in touch with them. I said, “Oh Man!”, it’s obvious what to do: If you have these three terminals, there ought to be one terminal that goes anywhere you want to go. That idea is the ARPANET”. Somewhat contemporaneously, several other people had (mostly independently) worked out the aspects of “packet switching”, with the first public demonstration presented by the National Physical Laboratory (NPL), on 5 August 1968, in the United Kingdom.”
“The initial ARPANET consisted of four IMPs:
University of California, Los Angeles (UCLA), where Leonard Kleinrock had established a Network Measurement Center, with an SDS Sigma 7 being the first computer attached to it;
The Stanford Research Institute’s Augmentation Research Center, where Douglas Engelbart had created the ground-breaking NLS system, a very important early hypertext system (with the SDS 940 that ran NLS, named “Genie”, being the first host attached);
University of California, Santa Barbara (UCSB), with the Culler-Fried Interactive Mathematics Center’s IBM 360/75, running OS/MVT being the machine attached;
The University of Utah’s Computer Science Department, where Ivan Sutherland had moved, running a DEC PDP-10 operating on TENEX.
The first message on the ARPANET was sent by UCLA student programmer Charley Kline, at 10:30 pm on 29 October 1969, from Boelter Hall 3420. Kline transmitted from the university’s SDS Sigma 7 Host computer to the Stanford Research Institute’s SDS 940 Host computer. The message text was the word login; the l and the o letters were transmitted, but the system then crashed. Hence, the literal first message over the ARPANET was lo. About an hour later, having recovered from the crash, the SDS Sigma 7 computer effected a full login. The first permanent ARPANET link was established on 21 November 1969, between the IMP at UCLA and the IMP at the Stanford Research Institute. By 5 December 1969, the entire four-node network was established.”
