One solution: normalize desk-rejections. After a fast first assessment, papers are either desk-rejected, or go to full review. The current conf peer-review system has desk rejects as the exception, as it relied on self-selection prior to submission and small numbers. Neither of these hold anymore.
Peer review relies upon reciprocity - I'll check your work, knowing that you'd do the same for me. Your investment in writing deserves my investment in reading. However AI generated theory papers are really testing my patience, and my peer reviewed faith. #ICLR
