I have to disappoint you, however, bigthink.com is already taken.
Those big talking folks at bigthink just published a collection of 'visions' by so-called experts and ask us (yes, me, you, the plebs!) which one of those visions might influence 'the world' the most. We are allowed to cast our vote. The visions come in handy in easily understandable little video-clips. Just in case we are too stupid to read.
Those 'visions' are stunningly unimaginative: eternal life, robots, fusion, extraterrestial life,...
It is hard to continue watching (or reading the computer-transcripts that no human eye has ever bothered to check) after you sat through the utterances of Ray Kurzweil trying to sell his book-series by claiming that a nutritional supplement of 150 pills a day made him come out close to 40 on a biological aging test, while his passport shows he is 61. Well, watching the video - with no additional information I would have guessed he is, ummm, 60 or older. A combination of food supplements, genetic engineering and, finally, nanorobots in every cell, he believes, will give us a dramatic extension of longevity.
Who out there is willing and able to go through a major part of the soundbites and lend a hand to us vision-impaired? Any lucid (or acid) comment is very welcome.
