Learn English – a possible equivalent for *not worth the paper it’s written on*


What is a possible modern equivalent, in our internet, and supposedly paperless age, of the expression not worth the paper it's written on.

Best Answer

The idiom is still valid and still in use.

I and many people I know will say an email is not worth the paper it is written on.
This the fact that there is no paper just emphasizes the worthlessness.

The obsolescence of the terms of an idiom don't render the idiom itself obsolete. For example, being hoist on your own petard doesn't happen literally often nowadays.
