The article calls out that «the probability of life emerging based on known factors peaked about 13,000 light-years from the galactic center and 8 billion years after the galaxy formed».
A hypothetical civilisation may well have emerged with a head start of five billion years – a span of time sufficiently vast to allow for profound advancement, assuming favourable conditions and uninterrupted development.
However, I find the oft-repeated assertion – that alien civilisations have likely annihilated themselves due to traits as tediously predictable as short-sightedness, internal strife or some anthropocentric parody of self-sabotage – to be both intellectually lazy and philosophically barren. such a narrative reveals far more about the limitations of the human imagination than it does about the potential trajectories of alien life.
A more measured and plausible explanation lies not in self-inflicted extinction, but in the nature of the galaxy itself. Five or more billion years ago, the Milky Way could have been a significantly less hospitable environment – more unstable, more violent, and subject to higher stellar activity. One must also consider the precariousness of location: the galactic core, unlike the relative quietude of our outer spiral arm, is a congested and perilous stellar thoroughfare, far less conducive to the emergence and persistence of complex life.
To default to the notion of civilisational self-destruction is to betray a lack of imagination – or worse, a projection of our own inadequacies onto the cosmos.

i can't help thinking the galaxy would be symmetrical with earths, like petals round a flower, being at the same stage of development as each other.
