We should expect some degree of similarity, at least at the social and cultural levels if not biological. We are not special so why should we expect other being will not be like us?

And yes I would expect them to develop computers of some sort (imagine typing to run our present global telecommunications system without computers), along with radios, fridges, cars etc - according to their needs / number of legs, ears or fingers. They will probably develop forms of religion and politics that we will recognize along with the novels, pop songs, opera and theater. And again we will probably find parallels - there will ge a Vogon Pinter, Shakespeare and Hurst. There will be romantic sonnets, stirring ballads and wordplay.

Why should they be different from us?

Of course that is also a caution.
