Justice, according to one definition from antiquity, is carrying out one’s duty to one’s station. Plato did not strictly speaking have only professional specialization in mind, and he was probably not thinking about justice in the way we have come to think of justice. As a general rule, however, it was agreed that minding one’s business and perfecting one’s trade were positive attributes that would advance the health of a society. There is a lot to be said for this, even now, but it is also possible that Plato, who anticipated many things, did not anticipate confluence and falling barriers.
For several decades now of an economy that is increasingly powered by services, we have seen service providers increasingly compete on the basis of specialization. To play a generalist role, for example, in consulting, finance, law, medicine, may have its place, but is not nearly as valuable – when push comes to shove – as proving one’s mettle in a concentrated field. Because service providers tend to follow the course set by their clientele, for many specializations this pattern has been in imitation of underlying industries. A sector such as technology, for instance, that has included memory chips and turbine engines and biotech research and Google’s algorithmic products, is clearly too vast to either operate or be served in a generalized fashion.
But an undercurrent is now beginning to stir, causing some of these sectors to blend and overlap. Whether Amazon, say, is more properly speaking an Internet company or a consumer retailer, and whether the Internet is a sub-segment of technology or media, are increasingly fuzzy judgment calls. There used to be a distinction between traditional media and new media, but that’s even going the way that apps and mobile access leads the two categories in tandem. Hardware and software are migrating towards one another as trends in open-source and 3-D printing take hold; and financial markets and info-tech are converging as themes of democratization and access do likewise. In the case of markets there even seems to be a movement of asset classes towards one another, as large institutions do smaller deals, as illiquid investments are made more liquid, and as the distinction between early- and late-stage diminishes and fizzles.
It’s hard, in such an environment, to stay true to the Platonic ideal. And one might even say that to do so would be to do one’s chosen field injustice. A narrow perspective, picked up in whatever classroom one has continuously sat, as it were, becomes a constraining and counterproductive feature. But it is equally hard, on the other hand, to break the hyper-specialized mold in which many, as a matter of course, have been shaped. This requires a perpetual education, re-education, and expansion. More than expertise, perhaps, success in such an environment is determined by one’s ability to adapt. And to take this argument one step further, this ability to adapt may be an expertise in itself, perhaps the most important there is, requiring hard work and special training.
