"Replaced with" or "Replaced by"?

[Tgthk]

I am reading a article about virtual team and seeing this segment:
"the reality of the workplace has been replaced with the virtual
workspace; the concept of work share, replaced by the concept of mind share."
It really makes me confused about the use of "replace" as I am accustomed to "replace .... with ...."
Please help me to make clear the use of "replace" in that case.

Hi tqthk,
Both of them are correct, look them up from the dictionary.
