What is the difference between an engineer and a normal people?

Here, i am not really elaborating the difference between an engineer and a normal people. I just wanna show an example to illustrate how an engineer and a normal people think differently.

ATM machine, i believe everyone who reading this post uses it before, and more than one once. But why is it so special to talk about it here?

To an engineer, the first thing that he/she want to do to ATM machine is how to make the processing of money quieter and quieter, or even soundless. That is a great thing for an engineer to think about.

However, why we still havent seen this kind of ATM machine before? Actually, there is a reason for it. And this is considered as a normal people's thought. It will be scary that we cant hear anything when ATM machine is processing the money as we will wonder whether the ATM machine is processing the money or not. And the next thing we will do is keep pressing those buttons and trying to figure out why ATM machine isnot processing the money.

This seems like a joke. but it is really true. think about it.

Love and Support,
