Three~five experts specifically asked to review a paper in a controlled environment versus a thousands random scientists or public people (which might be motivated by financial, malicious or other reasons) is probably still the better option. Larger, technically impressive multi-disciplinary papers with 20+ authors are basically impossible to review as individuals, you would like a few experts on the main methods to review it together in harmony with oversight from an reputable vendor/publisher. Such papers are also increasingly common in any biotech/hard-tech field.
I think ML (and really all other fields) are the same. Skimming a paper never really leaves you certain of how rigorous it is.
I agree that a naive "just add voting" "review" mechanism would not suffice to replace journals. However there's no requirement that the review algorithm be so naive. Looked at differently, what is a journal except for a complicated algorithm for performing reviews?
> I am afraid the need for these publishers will still be there and they will just exist regardless, and it will still be preferred by academics.
Agreed. I doubt publishers are going away any time soon (if ever) regardless of how technically excellent any proposed replacement might be. I still think it's worthwhile to pursue alternatives though.
Another issue when going to a decentralized tool is that I think it should apply some sort of gate-keeping to only allow academics or verified scientists to contribute reviews, but then you also need a way to prevent bias/friend/self-citation network interactions between the academic reviewers, which means you would need to keep good track of them? Not sure how to handle that.
