The idea is that the immutability of the operating system leads to greater stability. The partition should (in theory) be exactly as the distribution expects on every computer it’s installed to, which limits the potential for user changes breaking anything. The benefit to the user is that it’s a lot harder to shoot yourself in the foot by running the wrong script.
The issues have been described as login/logout, but I'm not sure that's all that's happening. In today's outage and the last the API stopped and kicked the session out.
I only mention this in case someone from Anthropic perhaps isn't aware that it seems to be a wider issue than login/logout (although I'm sure they are!)
You can use a picture of anyone's handwriting. There's high res pictures of medieval monks handwriting and so on that probably would be really cool as fonts.
