I’d take the Wikipedia answer any day. Millions of eyes on each article vs. a black box with no eyes on the outputs.
It's all about trust. Trust the expert, or the crowd, or the machine.
They're all able to be gamed.
Only a minority of users contribute regularly (126,301 have edited in the last 30 days):

And there are 6,952,556 articles in the English Wikipedia, so an average article is corrected every 55 months (more than 4 years).
It's hardly "Millions of eyes on each article"

(And also: each editor has (approximately) 2 eyes :) )
