Honestly, as you disagree at present, I'd try to have conversation and interests in other things. There is so much none of us can know about how it will develop over the next few years. Don't let hypotheses spoil your good relationship. If he seems keen on argument, just bat it away with a few 'Well I really don't knows' - we don't do we, any of us.
