True. But time and engineering doesn't make everything possible, and if something is possible it doesn't always make it likely. The world does have limits both practical and theoretical, contrary to what the popular mythology of progress implicitly suggests.
I just found this on slashdot:
"U.S. Views of Technology and the Future - Science in the next 50 years" by the Pew Research Center
This is interesting esp. in comparison to the recent posts on forecasting which focussed on expert forecasts.
What I found most notable was the public opinion on their use of future technology:
Don't they know Eutopia is Scary? I'd guess if these technologies really become available and are reliable only the elderly will be inable to overcome their preconceptions. And everybody will eat artificial meat if it is cheaper, more healthy and tastes the same (and the testers say confirm this).
