28. 70s : Models, Views & Controllers with “Aliens” “ Disney multiplane animation 'in 2s' ” Can “Ants” Be “Induced” To Do More Interesting Things? Ted Kaehler, Yoshiki Ohshima, Alan Kay Viewpoints Research Institute Glendale, CA 91201 Ants are a “distributed hive animal” whose “cells” communicate by a variety of means including laying down trails of chemicals which can help ants without food to get to discovered food sources. We want to investigate whether the “particles and fields” style of distributing messages as intrinsic parts of environments can work well for some programming problems. Figure 1: Ants swarming around food Figure 2: Simulation showing diffusion If we ask 5 th graders to help us think about this and act it out by wearing letters on their T-shirts, they quickly discover a good way to do this. For example, could we program a text layout and editing system just using a “field of messages” that individual text characters can sense and respond to? Laying out a “paragraph” of “ants” seems like a good place to start because it will have to work continuously while the editor is being used. It's really just “follow your leader” (and if you have no leader, then just go to the upper left hand corner. This works until the right margin is exceeded, so all the characters have to notice when this happens and pass this knowledge along to their leader. This happens until a leader's leader can be separated (for example, it might be a space). Then the leader can start a new line. We can make this look fast by doing it in between frame times – but it's also fun to watch!

Preface These are the slides and commentary from a talk given to the Research Board. As an experiment, I decided to try to write a coherent essay using the slides as a sequence of topics. The essay form is quite a bit more efficient than talking, so there is considerably more content in the narrative than in the talk – and the narrative also covers more than the talk. Many of the observations in the narrative did not appear at all in the talk. The result is kind of a hybrid – it's not what I would say in a talk (or did say), but it is also not what I would write in an essay (because tying the narrative to the slides precluded using a number of examples that would not work at all in a talk, but would be perfectly amenable in an essay). I hope that the hybrid will be of some use – and in particular will provide motivation for downloading and reading several of the essays we have written about this and related subjects. Alan Kay is one of the earliest pioneers of object-oriented programming, personal computing, and graphical user interfaces. This work was done in the rich context of ARPA and Xerox PARC with many talented colleagues, and has been recognized with the: Charles Stark Draper Prize * of the National Academy of Engineering “for the vision, conception, and development of the first practical networked personal computers” Alan M. Turing Award from the Association of Computing Machinery “for pioneering many of the ideas at the root of contemporary object-oriented programming languages, leading the team that developed Smalltalk, and for fundamental contributions to personal computing” Kyoto Prize from the Inamori Foundation “for creation of the concept of modern personal computing and contribution to its realization ” *with Butler Lampson, Robert Taylor, and Chuck Thacker
If we take a limited view on “now”, it seems to be not too different than the near past. Our minds are well set up to think of changes as either not happening at all, or happening incrementally on a pretty smooth slope. In the 20 th century especially – but really since the industrial revolution was fueled by the synergies between the new sciences and the older engineering skills – most changes have not been gradual. McLuhan quipped that the 19 th century was when “change changed”. The result is that what appears to be gradual using a narrow view is very often a tiny part of growth that is exponential.
“ Point of view”, “perspective”, “context”, “outlook”, etc., provide a kind of extra nervous system to the biological abilities of our all too human minds. Enormous amounts of effort can be (and have been) expended on weak points of view – basically trying to continue forward against great difficulties rather than looking around for better paths, and especially looking in another dimension (for example, “up” rather than just “around”). The metaphor of the “blind spot” appears here. If not enough care is taken, many useful paths, ideas, phenomena, methods, etc., (a) will simply be invisible, and (b) the “blank” will be filled in with weaker perspectives that will cover up even the awareness that there is a blank. Both IQ and Knowledge can be enormous barriers to progress here. There's nothing worse than feeling smart when you are looking at the wrong things – almost as bad is thinking you know something (you might very well), if you need to invent new knowledge . Conversely, spending a fair amount of time just on context and “problem finding” rather than blind problem solving, is often the key to both great results, and being able to get those results with a lot less effort. This another one of those “Science and Math Wins!” exhortations.
