benefit humanity as a whole
The Borg from Star Trek fills that requirement. My headcanon is that the people from its home planet made an AGI with the given goal of “benefiting humanity as a whole”, and it maximised that goal by building the Borg - making humanity as a whole by connecting them to a hive mind and forcibly assimilating all other species to benefit humanity as a whole.

Why do you think those should be separate? That just destroys the network effect. Original OkCupid used to have everything. Amazon has everything. Facebook has all sorts of shit. They don’t split into niches.
