>we've passed a point where further access to what's left require greater cost, greater effort, greater energy This is exactly what was said before, and was premature, that was my point. It's technically correct that no new resources were created, but practically speaking, the new technology revealed resources we didn't know existed (or couldn't retrieve). The point is that we don't know how far this extends in the future. Reality has a way of making fools of anyone who naively extends trend lines.
