In areas of applicability where GenAI to now considered to be good/great, the pattern I've observed is a frighteningly rapid progression from "abjectly terrible", to "middling and mostly more trouble than it's worth" and then "good/great".

Agentic coding and image generation are probably the best examples of this.

There's no guarantee that this trend will be seen with virtual assistants, but if it does, we're on the brink of incredible. Dedicated personal assistants, that actually know and understand one's context and work well together, are unarguably hugely appreciated by those who can afford them.
