I agree with you. If necessity can be bought with the help from others, who cares to waste time and energy to to that ownself! As you said, it has both the positive and negative impact on our life.
We do many staffs in daily life for convenience but evrything we do is not healthy for our body and mind. It just brings short time comfort but in the distance, it can be harmful or even deadly. Our dependency on machine and technology is eating us gradually but we don't care if our life span reduce to zero one day.
We can do something that saves us a lot of time, but what we do in that time saved is important. Most of us, do not much of value.
