Entities and disciplines can communicate without being the same. An idea we seem to be losing, not in small part thanks to social science.
I'm genuinely curious what you are referring to here?
Computing requires a common language and a common understanding, as does any discipline where you are dealing with the real world. If you extend social theory into computing you WILL end up with people claiming it is discriminatory to privilege any ideas within the field. Sounds like a nightmare to me.
Also, as I've mentioned in another comment, the article is not advocating for computer science and social sciences to 'become the same', but to improve communication and mutual appreciation and knowledge. (The title is a bit unfortunate.)
What would be the cost of from moving CS away from its current home?
