That could be said the same about humans, if you took a bunch of uneducated children and just let them tell each other their own ideas with no one to teach them anything for real, they probably do at least a little better than the current fancy statistical spellguessers, but they probably won't do exactly great, because of the same issue of the blind leading the blind.

And really in reality we do have that actual problem to some degree with the presense of non-blind adults. Actual humans are a mass of mixed clued and clueless with a lot of bad input feeding output feeding other bad input around and around and around, not even counting the legitimate fair differences of opinion.

So it's a problem, but I don't think it's a fundamentally new or worse problem than we already have,and have already always had.

The fix is I don't think there is a fix for that any more than there is for the same thing in humans. There just will always be bad data feeding bad reasoning right alongside the other good data feeding good reasoning. It's probably wrong to ever expect anything else, and fail to operate from that assumption rather than the idea that there might ever be some resolution where we don't have to worry about that.
