Imagine this: you’ve “dated” 600 people in San Fransisco without having typed a word to any of them. Instead, a busy little bot has completed the mindless ‘getting-to-know-you’ chatter on your behalf, and has told you which people you should actually get off the couch to meet.
The memes are becoming real. 
they'll probably take information representing some aggregation of interactions for a user and make some scoring model that tries to learn from pairs of user data and outcomes (in terms of whether they successfully dated or whatever you do on these apps). 100% marketing bullshit, doing LLM inference for something like this would have costs spiral out of control FAST. But a scoring model is cheap, they have the data to make one, and it isn't really all that innovative either.
