I have forgotten how to count!

The other day I was doing a simple calculation, ten thousand something minus a thousand something. What a struggle it turned out to be. Why? Simply because I was doing it manually. When I finally got to the result, I was not certain that it was right because the number looks a bit odd. I tried again and this time got a different result! Tried again and got another result. That was the final straw. I had to turn to my hand phone calculator for help. Sure enough, it gave the right result which was different from all of my earlier results. What does it mean? I have lost the ability to count.
That is what technology is doing to us!
