Innovative and terrible product idea:
A mouth implant that automatically senses food/drink intake and releases flavors to optimize for your palate; it learns from your saliva production
Never again have to manually add salt to your food or sugar to your coffee, possibly in front of other people
Sensory sovereignty
Flavor cartridges are a subscription service; dentists sell/install/maintain, like Invisalign
We start off with sweet, sour, salty, bitter, and umami; version 2 includes capsaicin
