In several previous years I have rescheduled things so I can stay up until the problems are released in my time zone to see how high on the leaderboard I could get.
It is sad that the AoC leaderboard will now just be filled with GPT entries.
For example, try giving ChatGPT the problem statement of https://adventofcode.com/2021/day/19. What comes out is basically gibberish. It seems to completely miss that the scanners report their coordinates in their own coordinate system.
But if nothing changes in the rules/community the leaderboards of early and more straight forward problems will probably be filled with GPT solutions.
