The earliest openings are not health or finance. Those may be bigger markets later, but they are harder to enter because trust is lower, mistakes matter more, and users want more control.
The real early wedge is in high-frequency, low-stakes, preference-rich decisions where feedback is fast and people already outsource judgment to algorithms, friends, and influencers, like entertainment, media, food, lightweight shopping, and parts of travel. These matter not because they are the biggest markets, but because they generate the richest signal about the person.

So the strategy is not just to build a better media-specific layer. It is to use repeated, taste-driven decisions to build a cross-domain model of the person, then move up-stack from information assistance → decision assistance → life automation.
The wedge is not the final market. It is the path to owning the memory layer that future personal computing depends on.
