Prompts are getting a lot of attention at the moment, thanks to the AI boom. It seems worth noting, though, that prompts are a venerable old technology. They are good for real life too.
The practice of prompting is a handy lens through which to think about all sorts of common interactions—in principle, it has to do with providing some sort of stimulus in order to provoke a response. It seems useful to think about prompts as ways to test ideas; as little experiments.
An interpretation of a stimulus (the prompt) can be expressed in multiple ways, through multiple possibly legitimate responses. The testing of interpretations, and the expressions of responses associated with these, is very, very helpful for learning.
