Coca-Cola advertises itself as a “happiness machine” as something that brings people together, builds communities, creates love and friendship.
The latest slogan i can remember is “open happiness”.
I like fizzy sugar drinks as much as the next guy but Coca-Cola is not liquid happiness.
Edit: Dropbox marketing slogan is “for all things worth saving”
Slogans are not promises, they are vague feelings. In the case of Coca-Cola, I know someone who might literally agree with the happiness part of it (though I certainly wouldn’t).
The promises of Theranos and LLMs are concrete measurable things we can evaluate and report where they succeed, fall short, or are lies.
