Am i right?!

Question

At the first steps of my learing programming i had some calculations and then some imaginations in my mind:
I knew that a signal movement speed in human nerves is about 100 meters per second then i compared that with computers which is 300000 km/sec
Then i concluded :
If i learn computer programming the computer will be in my service and this would be like 3000000 people are working for me!!
In some cases it is true but programming complications and offcourse malware make computers slower than humans!!

Answer 1

Just my opinion:

The metaphor of having 3000000 people working for you isn't really accurate, because even if you do have that amount of manpower to complete a single arithmetic task, it would theoretically take the same amount of time for approximately 100 people to complete it. This is because humans are separate entities which process data individually - Computers on the other hand can be programmed to synchronize perfectly to achieve parallel processing.

That said, human errors also exist, as a counterpart of programming complications and errors in computers.

Answer 2

Consider how many staff do Microsoft or Yahoo! or Google or Nasa! have!! ..
