You can do CPR without a computer system, but changing systems in the middle of resuscitation where a delay of seconds can mean the difference between survival and death is absolutely not ideal. CPR in the hospital is a coordinated team response and if one person can’t do their job without a computer then the whole thing breaks down.
If you're so close to death that you're depending on a few seconds give or take, you're in God's hands. I would not blame or credit anyone or any system for the outcome, either way.
Judgement is always part of the process, but yeah running a routine code is pretty easy to train for. It's one of the easiest procedures in medicine. There are a small number of things that can go wrong that cause quick death, and for each a small number of ways to fix them. You can learn all that in a 150 hour EMT class.
