the article is poorly written it has nothing to do with a reader's iq it has to do with the ability of the writer to convey the information in the simplest terms ergo it is the writer who is lacking in talent iq and not the reader you can compare two math books and you will see most people can't understand higher math because the guy writing it can't understand how to convey information in simplest terms the goal is understanding and not obfuscation or worse to show how 'smart' the writer must be if the writer can't clearly explain what cloud computing is in words or less the writer shouldn't be writing about it
