I think it's reasonable to ask, philosophically, whether the kind of values society and the socioeconomic system as it is configured encourages us to express are the kinds we really want to have as a species, etc.
But, as you in effect point out: From a capitalistic perspective, total, narrow commitment of the sort being chastised here is much more desirable and stands a higher chance of being amply rewarded than being a jack of all trades and a master of absolutely none.
Whether we want that kind of world is one question. But there is no question as to whether hackers participating in this world and structuring their lives to follow its built-in incentives are doing the best they can for themselves, in terms of the parameters of "success" as espoused by this system. They are.
