 Diminishing human agency: Another argument suggests that the effect of enhancement will be to diminish human agency by undermining the need for real effort, and allowing for success with morally meaningless shortcuts. Human life will lose the value achieved by the process of striving for a goal and will be belittled as a result (see, e.g. Schermer, 2008; Kass, 2003). Although this is a promising form of argument, more needs to be done to undergird the claims that effort is intrinsically valuable. Recent work suggests no general argument to this effect is forthcoming (Douglas, 2019). After all, few find compelling the argument that we ought to abandon transportation by car for horses, walking, or bicycling, because these require more effort and thus have more moral value.
