You aren’t in the business of twiddling the dials, even though the dials may still be important. This episode of the Tech Field Day podcast features Guy Currier, Jay Cuthrell, and Alastair Cooke. Knowledge of all the dials and controls has historically been a defining characteristic of infrastructure experts. The introduction of infrastructure as a service, then as code, and policy as code have shifted focus to more abstracted controls. Do these abstractions reduce the value of knowing every feature and setting, or eliminate the value of technology specialists? Generative AI and business-as-code may spell the end of the dial twiddlers. Optimizing every setting at every level in an infrastructure and application is probably not valuable to business, but there are still places where maximum business value comes from detailed knowledge of those dials.
