Oil will be a valuable feedstock for the forseeable future. Look at all the plastic in your house, in your clothes, in your car, wrapping your food, coating your circuit boards, the list goes on. Yeah, that's oil. Shame we can't harvest the plastic from the oceans and reformulate it into something useful.

Why not?

I haven't run the numbers, but seriously doubt it is economically viable. Most of the ocean plastic is small particles and it'd have to be collected, filtered and dried first.

Those first two can be done passively, or on the go with solar power.

Diesel and jet fuel by themselves account for over 30% of global oil consumption. Even if we get all other vehicles running on something else (ha), big trucks, freight planes and air travel will be guzzling oil for probably as long as we still have some left.

But oil products can be produced from biomass and energy too. And is carbon neutral, and doesn't have the potential side effects of extraction leaks and fracking concerns.

Oil isn't magic, it is straight up organic buildup put under heat and/or pressure. You can make 'fossil fuels' out of trees, grass, frogs, people, ect. It is just limited by our ability to produce energy which is currently our biggest restriction on pretty much every industry in the world and is what we are most concerned about solving.
