I feel like the topic has been discussed ad nausiem but:
* Software security - I.e. Mozilla blog post on using Mythos for software security [1]
* Algorithms - AlphaEvolve makes real progress on matrix multiplication [2]
* Open source - Backlog crushing in openvpn [3]
* Corporate - CloudFlare Oauth workers [4]
People are clearly using AI to ship real work that people end up using directly or indirectly. Projects like Godot are also in a weird spot though.
