Rebuild The World
With Nix, you don't even have to imagine that you can build the digital commons from scratch. One change to the bootstrap, and you'll rebuild the world. But, it's your world, and you can see every leaf and branch of the Great Tree in front of you.
In a world full of unwanted app updates and SaaS providers who want your personal information, being able to self host one of the largest collections of software on the planet in a stable way across updates with NixOS has the potential to change the game for anyone who's tired of the slow decline of cloud services. With a single line of code, you can enable replacements for services as varied as Google Photos or Slack, and deploy them repeatably across as many machines as you want.
Even if you don't run NixOS, building software with Nix allows you to deploy it across different Linux distributions and architectures. No longer do you have to build entire distributions into Docker images or flatpaks that bitrot - Nix can do that too, and it can do it over and over again. Set up a development shell to provide friends or coworkers access to dev environments, and build your software the same way every time, with upwards of 120,000 packages you can leverage.
Access to services and software everywhere: that's Nix. We've come a long way since Eelco Dolstra's 2006 PhD thesis. Welcome to Nix Vegas, where we want to rebuild the world.
