but the assumption you are making is that the underlying ideas are compelling. In practice, people often decide to publish incremental and/or mediocre work for various reasons, and then dress these ideas up to seem as compelling as possible to get past peer review or make a press release.

at the least, this is problematic for peer-review because the absolute number of submissions outpaces the time availability of a finite number of expert reviewers. We cannot quickly generate expert human reviewers, and so the community might converge towards half-baked solutions (AI-generated reviews or rejection systems, vastly expanded referee pools, etc.) that tend to erode trust and and make scientific communities more adversarial.
