I think it's fairly common for people to assume that something is easier than it is if they don't really understand it.
For example, a concert pianist makes playing the piano look so easy - an oversimplified statement might be "All you have to do is push down on the keys and the music comes out!" Of course almost everyone would understand that this is a bogus statement although technically it is true. However when you begin to enter into more recent technology such as photography the statement might be "All you have to do is point and shoot!" or with computers "Oh, the computer does the work for you..."
Now, relating this to computers... my wife is a professional graphics artist. She continually gets the "Well, you just push buttons and the computer does it for you" comment from her mother who is a traditional artist in the areas of painting, sculpture and various crafts. Her mother doesn't really understand what's going on with the computer, so she makes an ignorant (yet technically true) assumption. Yes, my wife does push buttons and the computer executes the commands. However there are thousands of buttons to be pushed, and you have to know exactly when to push them. Further, all of the myriad of creative decisions must be made just as in painting, sculpture, music... and even photography.
