For me it's about tolerance. When I was 13, I could and would customize everything, so much that the computer repair shop told my father that their son "likely is a hacker or something".

At 40, I could easily configure claude code to use another model, even if there weren't any official guides with a bit of MITM fun, but I don't want to invest my attention / heavily use something that will most likely break in the near future.

The real question is: should the file be edited in emacs or vim?

It's crazy that apparently doing math without knowing how to do long division by hand is normal now.
