In that case, perhaps we might be able to maintain close friendships with significantly more people. But given that even cognitively enhanced versions of ourselves would be constrained by the number of hours we have for socialising, increasing our number of close friends would need to involve wringing more intimacy from the time we spend with each friend. Or, it could be that a cognitively enhanced world would come with other changes, such as a reduction in working hours, which could free up more time for friends.
