Make a fun little christmas calendar to bring joy to the people, get turned into a gamified warzone where people use AI and bots to try to get onto the global leaderboards - possibly because getting on them might net you a job at FAANG
This also ties into the comments that AoC has become moot or was "ruined by LLMs". If you enjoy solving the problems, nothing should have changed for you. What's the difference if a given problem was already solved by an LLM, or a group of IQ 200 superhumans from MIT for that matter?
As time marches on, there will eventually be absolutely nothing left where an unaugmented human outperforms a machine. That doesn't mean you have to stop enjoying things. In a few years at most, all programming will be purely recreational.
That's a bold prediction given how much LLMs suck at programming today (and haven't really improved, either). I'm willing to believe that we will someday invent an AI that can program better than humans. I don't believe it'll be within a few years, because the current architecture shows no signs that it'll ever be able to get the job done.
I will search for a pure C private group to join that only allows a small library for things like reading the input as an array of strings.
Next week, I will be 64, and I am no longer searching for a full time job. In the past decade I only worked for 24 or 30 hours per week. I am financial independent and plan to only work freelance if there is some opportunity. Currently, I am not actively searching for a job.
The basic rule is: you are only allowed to use code you wrote yourself. That does include code you wrote before the start of the contest, for example, standard functions you wrote for earlier AoC editions.
