alt Hacker News> How does that have anything to do with peer review?
I already addressed this. People know peer review can be bad, but some think "good journals" still do good peer review. This is not so clear.
> In what world does the arxiv system moderate this discrepancy?
Open systems allow the scientific community to figure out ways to properly assess research quality and value more cheaply, and without passing through (often arbitrary and random) small numbers of gatekeepers that don't even do a reliable or good job gatekeeping in the first place.
Your argument depends on worse peer review at top journals - but fundamentally, you fail to show how doing any peer review is strictly worse than doing no peer review.
I understand that we want arxiv to exist, and it does, and it’s growing. That doesn’t mean we don’t want Nature or Science to triage the most compelling stories.
Importantly, we can already begin the search for these ‘cheaper’ review strategies while not losing the helpful information filter we get by seeing where things are presented/published
