AI will improve more rapidly than you imagine it will. Open source has been built around rituals that will go the way of the LP: for the nostalgic enthusiast only. This project already shows nobody cares enough now, let alone a year from now.
AI is already better than 90% of my colleagues, and none of them can write an exploit, or instantly draw on the breadth of information it can. So all they do is chaperone. Well, that will be gone too in a few years. What will remain are example repositories that serve as the starting point to add your own special feature. The curated set may well become private again, as a competitive advantage.
