Being inside the content does not make it a "modern system".
Actually, it's a rather dumb idea too, except for very simple systems. Besides editing the content (title, body, etc) there are numerous others things to configure and edit that don't normally appear in the content area --so they would be out of place there.
But the bigger problem is that you have to navigate the content as an end user would in order to edit it. A specialized screen with filters, columns, search et al would be much faster to work with.
Editing title, body etc. is probably the most used tasks in a content system. Do you disagree?
Working fast is great, but with filters, columns and searches your adding complexity. We love working fast with complex systems. They don't (is my thesis).
