If you're ugly you're not getting matches anyway. It does nothing for ugly people. At the end of the day a person has to be attractive to some positive degree in order to find a partner.
A person below the attractiveness threshold gets basically no matches, so no chance to talk. A person above the threshold gets a huge number of "already motivated" matches, so no need for good talk. Conversation quality only matters for the small number of marginal cases (maybe 20% of users)
The funny characteristic was that the number also matched me with my long term girlfriend and got him a single girl that he was interested in. I generally agree with your assessment, but I'd say out of 20% you still couldn't determine the AI user's intentions.
I've texted for my friends and I could get them a date or hookup but honestly when there's no motivation for them to do it themselves, it's a waste of time, they were not interested except to determine their conversation skills were the issue and not their looks.
