Depends on how much competing interest is out there.

A Petri dish might dream of taking over North America, but the humans might have other plans (for instance, the autoclave across the room).

Maybe they'd reason that North America is entirely lifeless, since nobody has yet tried to communicate the secrets of the Universe to them in a (bacterially) intelligible language.

Honestly the Petri dish has better chances. The bacteria that inhabit one have the demonstrated ability to persistently survive outside of it.

>the galaxy, or at least the local group

The local group is bigger than the galaxy.

Fair enough, however the Fermi Paradox and the consequently postulated Great Filter are a thing precisely because the evidence of this competition should be present but is not.

You are certainly correct, I misremembered the terms. Substitute for the local regions of our galaxy: https://en.wikipedia.org/wiki/Local_Bubble https://en.wikipedia.org/wiki/Orion-Cygnus_Arm

Thanks! I hadn't heard of the Local Bubble before.
