Nothing to gain, and yet everything to lose :)
My own feeling is that the physically unsustainable energy system of profit, has come to forcing apart couples.
It does this to more effectively commoditise us, it divides us up and pits us against one another in competition, black vs white, gender pqr vs xyz, spectrum 1 vs spectrum 2, victims of genocide A vs genocide B, its all just humans vs humans.
Even the strongest of marriages, and even in older age, we are not immune from this. It's a kind of insidious rot that has happened, and continues, mostly outside our perception, if we were not already hypersensitive to it, maybe by earlier experiences in life.
Folk identifying themselves as suffering from this or that medical classification of "mental illness", or even as this or that gender, Left or Right, or wherever in between, are unwittingly allowing themselves / ourselves to become just more products, and agents of this fatal system, which absolutely is alive, as surely as ChatGPT is alive, we should understand these are emergent properties, and how this works with the free energy principle to be either something very bad (The profit monster), or something very good (ChatGPT), depending on their source of energy, if it's extracted from the planet, this is bad, but if added to the planet, like as done by plants, this is good.
To me it looks like the same fix is needed for all things - sustainable energy.
Fix that, and everything else is fixed, including the stability of human relationships, putting marriage back on the table again as something cool.
