To those who can't possibly comprehend how all of those words and images miraculously appear on such a flat little screen, your power is great. You have the ability to perform virtual magic. If you were to take your laptop with you to King Arthur's court, you'd get quite the reception.
As for your power among your peers, that depends on whether you're working for the Man, or striving to become him. If you have the next Google (not Google 2 but something equally as useful and ultimately successful) and you are building it yourself, there are no boundaries for how far you can go and how powerful you can go. If, on the other hand, you are programming computer versions of popular daytime game shows, your access to power will be limited. Want to make a deal?
