Silly thought experiment. You’re a Stone Age hunter. You use a slingshot. Someone says they can make you one that shoots a little bit faster and weighs a bit less and has a sweet mammoth bone inlay that will impress everyone. You’ll have to pay a couple days of hunt. Would you do it? It’s a thing you carry all the time and it’s a big part of your “equipmental nexus” and thus your life and your real daily experience. Is it ridiculous to think of your phone as similarly crucial? Maybe.
