new developments in AI

sgs | academic,AI,review | Saturday, July 3rd, 2010

Thanks to popular culture, we have a good idea of what to expect when “strong” AI arrives. Machines attain consciousness? Prepare to be harvested as food. Detroit introduces talking cars? “Hello, Kit“.

What to expect in the near-term is less clear. While strong AI still lies safely beyond the Maes-Garreau horizon1 (a vanishing point, perpetually fifty years ahead) a host of important new developments in weak AI are poised to be commercialized in the next few years. But because these developments are a paradoxical mix of intelligence and stupidity, they defy simple forecasts, they resist hype. They are not unambiguously better, cheaper, or faster. They are something new.

What are the implications of a car that adjusts its speed to avoid collisions … but occasionally mistakes the guardrail along a sharp curve as an oncoming obstacle and slams on the brakes? What will it mean when our computers know everything — every single fact, the entirety of human knowledge — but can only reason at the level of a cockroach?

I mention these specific examples — smart cars and massive knowledge-bases — because they came up repeatedly in my recent conversations with AI researchers. These experts expressed little doubt that both technologies will reach the market far sooner, and penetrate it more pervasively, than most people realize.

But confidence to the point of arrogance is practically a degree requirement for computer scientists. Which, actually, is another reason why these particular developments caught my interest: for all their confidence about the technologies per se, every researcher I spoke to admitted they had no clue – but were intensely curious – how these developments will affect society.

Taking that as a signal these technologies are worth understanding I started to do some digging. While I am still a long way from any answers, I think I’ve honed in on some of the critical questions.

this week’s reading

sgs | review | Sunday, April 27th, 2008

I find the best writing almost impossible to read. Partly because I want to savor it; I want to deny it ends. Or, sometimes, it’s so provocative it forces me to reconsider everything before I can continue. But, mostly, great writing pisses me off because I didn’t — and I never will — write it first.

I had the painful pleasure of reading two such articles this week:


The Memory Master
by Gary Wolf

I have always insisted that Gary Wolf is the best writer in the WIRED stable, but evidence has been pretty thin on the ground recently. His profile of productivity author David Allen was starting to seem typical: an occasional spot-on sentence surrounded by otherwise very workmanlike prose, and a seeming unwillingness to really confront the big ideas he briefly exposed.

But in the May 2008 issue of WIRED, Gary Wolf kicks out the mother effin’ jams. His article on Piotr Wozniak and his algorithm to optimize memory is effortlessly brilliant. Part profile, part Eastern European ethnography; part software review, part scientific history; part reverie, part requiem. There are more substantive ideas in this one article than in a year of back issues.

But Wolf had better be careful — this is at least the second time he’s written subtly and beautifully about memory. His 1995 feature on Ted Nelson repeatedly returns to Nelson’s childhood memory of the “ephemeral eddies under his grandfather’s rowboat” , “how the particles would separate around his fingers and reconnect on the other side” as a metaphor for memory and its disconnects.

This means he’s dangerously close to being called “Proust-ian”, or “WIRED’s digital Proust”. And he’s better than that.


Spacewar, Fanatic Life and Symbolic Death Among the Computer Bums
by Stewart Brand

Yes, I may be the last person on the planet to read this screed from the December, 1972 (!!!) issue of Rolling Stone. It is a loosely narrated (it reads more like the notes for an article), journalistically uneven (some quotes seem… impressionistic), investigation of the future, based on what a group of  Northern Californian “heads”, drop outs, government agents, and self-described hustlers tell him over drinks.

And he gets everything exactly right.

One favorite bit is when he extrapolates from seeing a stoneage TTY, a 110 baud ARPAnet connection used to print an ASCII fortune on a tiny green screen. Then, with just one more sentence, he takes a giant leap that soars over the subsequent thirty years, and nonchalantly predicts the death of newspapers and record stores. (“Since huge quantities of information can be computer-digitalized and transmitted, music researchers could, for example, swap records over the Net with ‘essentially perfect fidelity.'”) 1972!!!

And it’s not just that he predicts today’s headlines without even the occasional whiff that would seem obligatory for someone swinging so determindly for the fences. It’s that he’s still ahead!  Even after reading the article today, you come away feeling like you have a little better feel for what’s to come.

Best of all, the article justifies my preference for learning from the margins. Sometimes I worry that I listen to hackers and other degenerates just because I find them more congenial; that maybe I should pay more attention to, say, what Steve Jobs thinks about streaming video, or, hell, read TechCrunch. But the richly predictive ore Brand mined from the “Computer Bums” says otherwise. In fact, so does he, in the article’s conclusion: “In our arrogance we close our ears to voices not our rational own, we routinely reject the princely gifts of spontaneous generation. ”
