I’ve always agreed with abiotic oil but would add that we need to determine the “balance point” of our use v. abiotic production.

That's long been my question as well. Once we know how fast it can be replenished, we know how to modulate the extraction rate to balance extraction vs production.

I suspect, tho, that we are still on the “up” side of that equilibrium curve.
