I'm currently 15,000 ly from the bubble, on the opposite side of the Pleiades. I've so far honked close to 6,000 systems and scanned 70,000 planets without seeing any trace of these aliens. If they're out there, fine. Good for them. If they want to buy my exploration data, the better.
But as far as threats go, they'll have to take a back seat, far behind humans and Neutron stars.
