Answers for 1) and 3) mostly mean "I don't believe technology will ever reach that point, and I will not believe any claims about safety/quality/taste/any other that they will make for marketing purposes. " In many historical cases "like margarine vs butter" this approach was totally right, and it can be right for driverless cars and artificial meat.
For 2) , most people would not use even proven safe imlpants unless forced to do so, like "get that chip or lose your job". Thank sci-fi writers for that.
proven safe
What do you mean with the term?
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).
