What is the advantage of a .ruby-gemset over using a Gemfile with Bundle?

Gemsets give you..
…compartmentalized independent ruby setups. This means that ruby, gems and irb are all separate and self-contained - from the system, and from each other.

Ok, but what advantage that gives you? All of the gems and ruby installations are practically immutable. They do not change in any way not matter what application is run (do they?). So there is no advantage.
Anyway were diverging 
Asdf work’s great with elixir, and any IDE/Editor I tried to write code in. If you need gemsets functionality you’re out of luck with asdf 
Just like you’re out of luck when you need full rustup functionality when using rust.

I used gemsets a lot before bundler was a thing. I think that they are just a relict from those days. Also they give you a separation of environments which can’t leak by design, no bundle exec necessary.

I’ve read that there are performance benefits; with gemsets you have just the gems you need for that application, without them, your ruby install could have hundreds of gems (who’s gem-specs need to be parsed) - so you get faster loading.
For chruby, there’s GitHub - postmodern/gem_home: A tool for changing your $GEM_HOME · GitHub
I haven’t used them myself as I’ve not run into any performance issues.

Just tried asdf and it worked like a charm. I’ll use it now for everything, many thanks for the recommendations!

article should probably mention installing elixir compiled against the installed otp version eg. something like asdf install elixir 1.5.0-otp-20 - so all features are available - read more here GitHub - asdf-vm/asdf-elixir: Elixir plugin for asdf version manager · GitHub

I install elixir with homebrew so if I want to manage elixir and use different versions I need to uninstall and use some of these managers and install again with the manager?
