I tend to agree with this. The leaderboard for many programmers is a source of stress and is another type of internet "comparison" like seeing someone who appears "better" than you on social media. Advent of Code, to me, is a celebration of all the hard work of the year by getting a chance to show off any new skills or abilities you might have picked up.

Advent of Code should be about the solve and the sharing of a good problem together, not how fast can you cook a plate of spaghetti.
