No he said that in the video. It's a moot point. We are looking at doing something new. Will it be price competitive once it matures? Thats what we need to be asking.

Because if yes, immediately shift ALL subsidies from petroleum to whatever CAN effectively replace oil-plastic.

Whatever we do, it has to actually be effective regardless of cost. Cost come down as economies of scale sort themselves out.

Plastic is killing us anyway, what cost matters if we are all dead?

This is a problem NOW. Paying for it is a problem LATER.
