There does need to be a mechanism to keep the human in the loop to correct the knowledge base by people who have the underlying knowledge. Perhaps notification needs to be sent to people who have previously viewed the incorrect information when a correction is made.
I’ll just address one point, the mining of minerals for solar panels. The lifetime for solar panels is at least 20 years. As soon as fossil fuels are burned, more fossil fuels need to be mined. First Solar claims to already have technology for recycling their panels that recovers 90% of the materials.
Points and responses like this are probably being repeated many times in different social and news media as well as in everyday conversations. IMHO, a top priority for humanity is building a global platform to merge these various forums, fact check and deduplicate claims, and aggregate sentiment expressed towards proposed solutions, to strengthen the signal out of all of the noise. This platform could become a form of collective terrestrial intelligence, which is desperately needed.
