You only need to know one tool !!!

One tool to rule them all

Developers focus on development

Reusability of tools between developers (even vim configuration)

Not needed to jump all into Nix. Gradual migration. Nixify only when it brings the value.

Reproducible environments without any virtualization/containers

Thank you

your tools will f*** you
whenever they get a chance
