… it’s the person using the thing.

I know Bob S. is talking about something else, but the word substitution does go to show something.

There is nothing magic. There is nothing that an object can do for you, in and of itself. In the end, it’s all about the person using the object. If a good person is using the object, good things can come from it. If a bad person is using the object, a bad thing can come from it. Using Bob’s words, if you have good and attentive doctors in the emergency room, they can save lives. If you have bad doctors in the emergency room, lives can be lost. It’s nothing to do with an emergency room itself, it’s all about the people in that emergency room. But even with the best doctors, lives can be lost… we are human, we can make mistakes, we can be distracted. But in the end, we’re still glad to have good people with useful tools at their disposal because in the end it keeps our society running better than if the bad people had the advantage.
