Starting at the end, the reason I think we CAN’T use our money productively is that we are 11 trillion in the hole and sinking fast. That’s why I am pessimistic about our capacity to use our money wisely.
New tecnologies are expensive. The oil recovered with these new technologies will be expensive, which makes drillable oil more profitable.
I also think you are mistaken about the renewability of oil. Everything I’ve read over the years indicates it takes eons for oil to form. Must have overlooked something.
