Graphene, other 31 million materials etc, all share a common risk. No way to recycle or unmake them.

I’d be more impressed if the AI could handle cleaning up a landfill of toxic materials. How about ways to take 31 million new contaminants in drinking water… out of the water? I am pretty sure you don’t need more material to reach high numbers of unremovable contaminants. There are probably enough contaminants in waters and soils and air already to pose a challenge for removing.
