This kind of dynamic has been going on since antiquity. Scripting will always have a niche, and 'enterprise-scale' development will too. Rarely it is based strictly on nuts-and-bolts practicality. Let's not forget: human beings are always subject to political pressure, the desire to feel 'knowledgable' and 'prestigious', and the desire to make things difficult for potential competitors through barriers to entry (turf preservation).

You see it in every realm of human activity, which includes programming and language design.

For people with a 'nuts-and-bolts' inclination, this "political" aspect can be a bit frustrating and bewildering. Nevertheless some PHBs realize that if they don't use Oraclefoo or Javawhiz for high-profile projects, there is a certain level of 'prestige loss' (and perhaps other issues) that cannot be quantified in mere nuts and bolts.

In some industry segments, this is not a major factor; but for universities, large corporations, utilities, financial institutions and other realms where prestige and reputation is the name of the game, you can just bet you are more likely to be Oracalized than MySQLated.
