The folks over at Edge annually pick an interesting question and let leading scientists and notables offer short essays to answer. It’s fun and truly thought provoking reading (I hate that phrase, but it’s true here so I’ll use it).
This year the question was What are you optimistic about?, but I found the answers to the 2006 question was “What is your dangerous idea?” even more interesting. My favorite answer to that one comes from Geoffrey Miller:
This is the Great Temptation for any technological species — to shape their subjective reality to provide the cues of survival and reproductive success without the substance. Most bright alien species probably go extinct gradually, allocating more time and resources to their pleasures, and less to their children.
You can read his full answer here (scroll down), as well as the full list of answers by other folks, including Howard Gardner, Jaron Lanier, Daniel Dennett, and Freemon Dyson.
On my first trip to London in 1996, on a whim from a blurb in some guidebook, I checked out Speaker’s corner @ Hyde Park. I just could not believe the blurb: a place where anyone could stand up on a box, preach or rant to their hearts desire, and throngs of people would come to listen, all for free.
Inconceivable!
In NYC, we had a name for public speakers – crazies. We’d ignore them, or as a gang of kids, terrorize them. As adults, who has the time to stop and listen? The notion was absurd, and in my then fully charged American arrogance I figured if such a form of free speech were possible, surely I’d have seen it before in America.
So I went to see for myself – It was true and it blew me away.
Many speakers were political or religious, but many weren’t. Some were pros who seemed to be regulars at the corner, but many were just working people interested in debate. The experience redefined what a public speaker meant. It’s one thing to speak at a conference or in an office where there are rules of conduct, but entirely another to speak where no one has any obligation to even listen to you.
I can’t say what goes on at the corner is a good way to debate issues, but it sure is an experience and any thinking person can’t observe what goes on there without some kind of opinion.
I’ve been thinking more about speaker’s corner lately for two reasons. First I now make a living as a public speaker, but also because of the rise of informal presenting, from un-conferences, Pecha-Kucha, and 99 second or 60 second university talks.
Surprisingly youtube comes up short on capturing the experience. But here are a few to watch if you’re curious (which you should be):
The question I’ll ask you is the same one I ask myself:

The talk I did at Lunch 2.0 a few weeks ago at the F5 office in downtown Seattle is now online. You can watch the video, or download an mp3/podcast. It’s an interactive Q&A about innovation and invention, ~45 minutes.
Fun stuff, no slides, and some good questions. One factual error: I claim Swift had the patent for the light bulb, but it’s Swan.
#4 on the free review list is SimplyGoogle a utility page, exploding out many of the google options onto a single page. Since there aren’t that many user tasks here, there wasn’t much to work with. The core problem with the page is layout – it’s an endless series of command buttons running down the middle of the page.
The easy remedy is the ever handy radio button: as a rule of thumb, if you can get away with one command button instead of ten, you’re making an improvement. You get tons of real estate back, and it’s easier to scan the list of options.
