Actually, I don't think it'll get much sharper, if at all, largely for the reason you mentioned. I think that what we consider to be "alive" will largely grow more fuzzy, but what isn't alive will be sharper. I don't find it hard to believe that a computer running advanced software (e.g. an advanced AI) is alive, but I find the idea that a piece of inert data (a virus) is alive to be counterintuitive and wrong.
