Imagine if you had a handheld device connected to the Internet that you could look at quietly under the table or something.
Suppose you were pretending to be a civil engineer and you actually don't know anything about the subject.
How long could you pretend?
I think if you know some basic science and had a good connection to the Internet, you could pretend to be a civil engineer (or a doctor, or a biologist, or anything!) for quite sometime. Maybe even months or years, before you are found out.
The handheld connected device could do to education what the calculator did to arithmetic.
The question is, if you know how to use a calculator, do you need to "know" arithmetic?
If you have google, do you need an education?
