Buying household groceries or anything of size sounds annoying or impossible on bike.

Not sure why buying groceries on a bike would be annoying or impossible. I do all my grocery shopping by bike, every single day, sometimes twice a day. Just bring a backpack.

As for ‘anything of size’, what would you need to transport? I still have a car, but I use it so little that I only need to buy gas maybe once or twice a year.

You can do all file management operations from the command line. No need to use the Finder.

Do you even git?

Surely experiment 1…n should be branches.

Why would you use the Finder when macOS has a perfectly fine shell?
