I understand it's alpha and I assume the problem will be solved along with the addition of party dialogs and love and hate system. But just in case it won't I wanted to voice my concerns. And the problem is: for me, after recruiting them companions feel like mindless bots.
I can assure you that you have nothing to worry about. The game is still very much an alpha, as such most of the companion/party dialog has not been implemented yet. Try to chat with one of your companions and you will see a message from the developers.
