Well said jungle drums.
The discussion and debate here and in other media serves to illustrate how people tend to get focussed on detail and ignore the big picture. That big picture is just so big that it cannot be dealt with by a few indivuduals or enterprises - it requires a generational change in mindset, attitude and outlook. Technically ignorant people seem to take the view: "Lets just hang on a while and some little boffin in a white coat will invent some gadget and then we can all go back to our previous profligate lifestyles" as they do not iunderstand the issues involved.
