I've been using NixOS for the last year and have loved it. Rebuilding doesn't fail for me nearly as often as it does for the author. Running nix garbage collection frequently isn't a big deal and can easily be automated. The network usage is a fair point. But IMO a small price to pay for keeping all of my devices perfectly in sync and running into weird "works on my machine" issues way less frequently.

My rebuilds fail all the time, but that's self-inflicted. I build my whole system from source with the nix binary cache disabled and optimizations for my processor enabled, so it seems like every update I have multiple failures which range from transient issues like GNU's savannah being down to persistent issues like software suddenly not compiling with `-march znver4`.

Reading the blog, they complain about compile times, which makes me wonder if their issues are similarly self-inflicted. The average user shouldn't need to compile software due to the nix binary cache. So they must have been either modifying packages or enabling optimizations.
