The problem with this is it's easy to say "we can't ignore our problems", and everyone will agree, but for most meaningful purposes that is exactly what is happening. We've been ignoring the problems and saying things like this for over half a century, while they continue to get worse. When does it become advisable to start ignoring the people saying "don't worry, it's not too late, we'll figure it out"? While this may still be true, it's a great way to rationalize putting off the massive social, psychological, legal and technical changes we desperately need.
