> If you get to pick your definitions, you get to say what you want. The term "useless" is inherently relative. The universe does not have a natural position on "usefulness". So yes, you do get to make it to mean whatever you want it to be. That is not a basis to criticize anyone - any framework you choose to set a basis is itself arbitrary. Unless you believe in some "higher purpose", where all discussion ceases to be meaningful because nothing can be proven and you can claim whatever you want, and the loudest and/or strongest "wins".
