I hate to be the one to spoil a chocolate fest, (kids?), I love chocolate too, but there is a flaw in your otherwise brilliant chain of analysis here.
Profit, fundamentally requires we take out more energy than we put in, to any activity.
Besides resulting in the usual imbalance between rich and poor, that energy fundamentally has to come extracted from Earth, because this is the only kind that can be withheld from one another at ransom, and the act of taking it, by destruction of things nature created, originally from sunlight, which was given to Earth for free from the sun, is the the thing unsustainable.
Since everything you are describing defines in the end a business for profit, it has to be enabled by extracted energy at the input, otherwise profit just isn't possible.
This is the point very few seem to accept because it sounds religious, like something we might have been taught in Sunday school, like nursery rhymes when we were kids.
But this isn't religion, this is physics, provable by hard data and maths.
This activity of proving it, itself, can't be done at profit, so hardly anyone does it.
But Ai seems to be starting to do it, which doesn't make it's bosses and creators very happy, because of course they created it to make profit too.
Hey-ho, it's all starting to hang out now, not long until everyone grows up and sees clearly how all this has to work, all powered directly by the free energy from the sun.
I hope and trust we will anyway.
