I think you're not reading it in the spirit it's intended. There's a section towards the end (Chapter 5, I think) that is full of policy prescriptions. But most of the encyclical isn't "about" AI, it's "about" Catholicism, and is using AI as a lens to talk about principles the church has been building up over a century. In that sense the document is less concerned with frontier models and disinformation than it is with establishing Catholic social doctrine --- subsidiarity, solidarity, the common good, etc.
As far as the church is concerned, AI as an issue will come and go, but the ordering and prioritization of human relationships is timeless, and is the important issue. The subtext of the whole thing is that if you get the principles right, the tech policy will fall into place.
You can argue with those principles, but at that point you really are just arguing with Catholicism itself, which is fine, but is besides the point.
(I'm not engaging with or disputing your takes on policy, only with your comment as a critique of the encyclical itself.)
Perhaps, but I think that's a bit generous. Let's look at Chapter 3, titled "TECHNOLOGY AND DOMINANCE. THE GRANDEUR OF HUMANITY IN LIGHT OF THE PROMISES OF AI."
This whole section is clearly about AI and social policy. It makes occasional Biblical references but if you strip those out it sounds like any Democrat podcast. If random people were given these quotes stripped of context, how many would guess it was the Pope?
For example: > What is needed is a more active political involvement that is capable of slowing things down when everything is accelerating
That's a demand for AI regulation.
Then take the paragraph that starts with:
> In many cases within the digital context, control over platforms, infrastructure, data and computing power does not rest with States, but with major economic and technological actors [snip]
The whole paragraph has nothing to do with Catholicism. It could have been written by the EU Commission and you'd never know. In it he appears to argue for the nationalization of AI labs, using standard progressivist claims.
Later the Pope argues once again for the nationalization of not just AI labs but all intellectual property held by the computing industry, using an argument I'm not afraid to condemn as theologically specious. In "The principle of the universal destination of goods" he says first that things like earth and water are given by God and thus everyone has a "right" to use them as they wish. From a theological perspective this is reasonable, albeit not from an economic perspective. But then he argues that patents, algorithms, datacenters and digital platforms are exactly the same as soil and water, and thus everyone should have them for free. That's nonsense. The religious justification for the first is that God made planet Earth, but He obviously didn't invent the transformer algorithm so why would the same logic apply?
All this is just standard left wing politics. The only theological justification I could find in the first part of this chapter is that some other recent Pope agrees with him.
I don't have any problem with Catholics or Catholicism. In fact I've written a whole essay arguing that AI raises issues only religion can deal with:

Religion has something to contribute when it comes to pondering questions like, what is AI? Does it deserve compassion and feelings, does it have consciousness and free will, or is it just a machine? Does the creation of it make us challengers to God or would He have approved of us making creatures in our own image? But the Pope doesn't engage with those topics. Instead we get advocacy for government power. The world has enough of such politics already.
