I can only repeat. If you take your prophesies from books written by people living in the Middle East, you'll find that they take place in the Middle East. Strangely enough, the divine information about the future that they were privy to never included stuff about undiscovered lands. They only told them about places they already knew about. Odd that, eh?
Thats a fair point which certainly explains why impending dooms of the past did not come to be.
I certainly don't rule out some new stuff opening up a world of new possibilities. However, I find it impossible not to be concerned when I look at what scientific progress has actually consisted of in the last 60 years.Its largely been about new and interesting ways to exploit hydrocarbons, and nowhere near enough signs of interesting new practical and scaleable applications of nuclear or sub-atomic physics. Its certainly possible to look at genetic stuff as having some potential to mitigate against things like lack of pesticides, or that we may be able to grow more medicines. A breakthrough could happen at any moment, especially when the will and desperate need comes to the fore, but we can't bank on it.
Our failure to progress further into space at a reasonable rate, including the exploitation of substances that are not from this planet, could be seen as one rather obvious failure of reality to keep up with our expectations.
If I had to guess right now, Id say that science is going to fill the gap on its own, we are also going to require a dramatic change of ideas, priorities, economics etc. Information technology has progressed quite well in recent decades, and thats likely to factor into all of this somehow, so long as we don't go off on a road of doom. For me doom, destruction and a return to primitive life are not certain destinations, the resource stats on their own don't lead us to that point. But a combination of resource issues and exceedingly poor human response (e.g. plenty of war) could, in theory. Don't expect everyone to buy into this at this point, don't mind if people point and laugh, it will be later on that this stuff really matters and where dismissal or poor understanding of the likely realities could lead to huge political error and much suffering.
