It feels like general-use LLMs, are all becoming very good for anyone looking to use them for daily use.
The thing that will separate them long term is a lot to do with data imo. Gemini has a great chance because its a pretty unintensive model (not like Claude going intense and for speed with searches etc).
Gemini has access to a full collection of data points, like Google Flights, Google Maps etc. Makes it quite easy to plan things for travel planning when everything is all in one. Funny that this literally never ends, and their integrations layer extends forever.
