Honestly I'm just glad that this declarative approach is steadily being realized. It hasn't hit mainstream adoption yet, but it gives me hope that this headline is making the rounds.

Docker is, as the article describes, just a bandaid and the symptom of unthoughful development foundations.

In the long term, Guix may win out. Probably not in my life time though. But it's a win for developers, and nix really isn't so bad with everyone vibecoding away it's complexity anyways.

I think they're two different tools. Containers are great for production environments. Beside reproducibility, they also give control over resources and manage virtual devices. Things that are rather not needed during development.

You can even generate Docker images deterministically with Guix. :)
