The document discusses replacing the term "computer" with "invocational media" to describe modern electronic devices that can be invoked to perform programmed sequences of tasks. It notes that while this gives users more power, it also reduces understanding of how commands are carried out. The nature of invocation allows users to stray from their intended tasks as they learn new functions of their devices, similar to how speech influences language development. The author questions whether replacing "computer" with "invocational media" strays too far from the original criticism of digital computers being obsolete.
