If they view us as interchangeable cogs, why wouldn't they view the technologies we use in much the same way? This was a big problem with healthcare.gov's launch, the CMS (government) had had success in a previous project with a particular non-relational database, and made the contractor use it, despite I'm sure essentially none of their people knowing it, and probably few if any even knowing the database's paradigm. I wonder how many "estimates" the contractor was required to supply to the government based on this.... (Although perhaps a bigger database problem initially was that it was severely underprovisioned, emphasized by how extremely specific they were about the hardware it was moved to.)
