Devcontainers aren’t better than Nix fundamentally, but people can get running with them in an hour and be productive, instead of Nix that’s a week long effort for newbies.
This is very true. There need to be a Nix guy in the team to bootstrap and be the evangelist. My experience is that in one week everyone gets very familiar with the workflow, and in 3 months all of my team become experienced Nix users.
Great.... How do you do that inside a 4 hour workshop?
