With the Alexa devices that have local processing hardware, that is exactly what happened (prior to this change, if you had the local only option set). But now, in the age of LLMs, there are no "simple rules". An example. Say you live in San Francisco: "Alexa, I'm thinking of going to New York, how many flights are there each day?" This is a hard question, and one that will go to the cloud. "Alexa, what's the weather" This seems like an easy question. But with local only processing, you'd get the weather in San Francisco. But with the LLM, it will probably give you the weather in New York, which is most likely what you wanted if you asked these things just a few seconds apart.
