If AGI had a drone army, why would it need them?

Can't help wondering if they've really thought this through.

I'm reminded of the scene in Independence Day with the people on top of the tower welcoming the alien spaceships. Except instead of celebratory fanatics holding poster boards saying "Welcome", it's all the singularity AI thoughtleaders holding hands in a circle chanting about Roko's basilisk like some new-age spirituality retreat.
