I don't think feudalism is going away one way or another. It persists [in various forms] because of certain biological realities, ranging from genetics to loyalty engendered by familial relations. [This is merely an observation.]
In sum, the argument against current AI trends isn't that once addressed we will wake up in utopia. No. The point is that these natural tendencies of humans are hugely amplified and set in generational stone once the elite have control over thinking machines and lord it over a population that has experienced generationally diminished independent cognitive abilities.
p.s. All this somehow reminded me of 'Spock's Brain' episode of Startrek /g Note: the elite there were overcome because Kirk and his landing team were cognitive high performers ..
I always thought the Butlerian Jihad was the biggest plot hole in Dune, but I deeply appreciate the world and narrative it enabled.
At the level of the text, none of those things you mentioned strike me as positive developments. They just siloed computation to a biological track and those biological resources are employed by those in power, which is the same problem in a different form.
This is an aside, but feudalism is not inevitable. The vestiges of it still exist, but capitalism largely upended it.
It may not prove to be effective or as momentous as the fictional one, but it began when I saw stickers slapped onto utility poles that read:
DEATH TO CLANKERS
BUTLERIAN JIHAD NOW
And I stopped to read them (because they were posted in a neighborhood where my people's cultural center is) and I pondered the intents and methods of those who were slapping up stickers. Surely this was more than just an in-joke or coy sci-fi reference?The next time I fell victim to the jihad was with a crop of Lime e-Scooters, again on a block where my people have established businesses. I wanted to rent a Lime. I found one with a full battery. I located it and tried to scan the QR. Guess what? The QR had been sanded completely clean. There was no code, no serial number, nothing to scan and no way to uniquely ID the conveyance. There was only a sticker slapped prominently onto its side:
DEATH TO CLANKERS
BUTLERIAN JIHAD NOW
At this point I began to suspect the initial aims and methods of the "real-life Butlerian Jihadis". It is sort of ironic that they should start so small, by denying micro-mobility to innocent consumers, but perhaps they will graduated to lighting Waymos and Teslas on fire.
