I talk to an Si dom sometimes all day long.
My ESFJ ex and I, one of our main points of connection were our long conversations. We still write each other long e-mails sometimes.
There's this thing apart from MBTI called "shared interests" and it seems to me you're presuming that the Ne dom has not developed their Si (and perhaps you haven't) and the Si dom doesn't use their Ne.
But sure, okay, what would I talk to with an ISTJ about all day long? I've got no clue. I've never been put in such a position. My grandfather wasn't very talkative and his idea of spending time together was each reading a book on seperate chairs in the same room.
