Earlier quoted context omitted.
Can you tell me more about "curl-to-bash"? Setting up my mac can be a matter of days and I hate it.
I think they mean the classic install process of "curl -s | bash", used to download and then execute a bash script. The real question in my opinion is what kind of tools can fully set up an entire environment, including sessions, from a bash script? Homebrew only gets you so far.
Homebrew has an app that can also handle installing Mac App Store apps. It also handles installation of third party fonts.
You then download and activate your dotfiles, copy over your data, and that's it.
For sessions, I guess a download of a recent cloud sync of your last tmux state for iTerm2 would do it (haven't tried).
