I find it interesting how a lot of cyberpunk does not really include AI or does not present it in transformative way. There is a lot of mind uploading, implants, corpo fun and overall technology permeating all aspects of life, but often AI itself does not actually play a big role.
Counterexamples that come to mind are Neuromancer (AI driving the plot) and Blade Runner (AI antagonists.)
A compromise thesis might be that in cyberpunk media, AI is at never powerful or motivated to fundamentally reform the worldwide crapsack economic system. They don't abolish corporations, although they might take them over.
Of course, if there was a story about an AI taking over the world into a post-scarcity society, it probably wouldn't be filed under "cyberpunk" either...
Rampant capitalism is kinda genre-defining for Cyberpunk so Cyberpunk without corporations wouldn't really be Cyberpunk. _The Matrix_ only qualifies as Cyberpunk because within the matrix the machines effectively control the capitalist power structures to exert their influence.
Abundance/scarcity isn't really about availability, it's more about access. You can have a cyberpunk story in a "post-scarcity" setting in the sense of availability (due to sci-fi tech) but you can't have it without unequal access to those resources.
It is a pretty core part of Cyberpunk the "franchise" though, both tabletop and more recent video game.
I think as well if you look closer, many cyberpunk worlds imply AI through robots, computers with personality etc.
AIs are in plenty of cyberpunk stories, but your comment did make me think that they are often rather stereotypically “alien entity characters” and not a kind of corporate technology / weapon that is controlled by a specific organization.
Which is a shame, as it seems to me that the overwhelming risk of AI is from the latter scenario, and not as a rogue individual entity.
AI is one of the core parts of cyberpunk, through androids / humanoid robots. Blade Runner is completely built on the protagonist having to interact with rogue artificial intelligence.
I find that more realistic then, because it appears that's the trajectory we are going on with regards to AI, as a tool not a panacea.
I assume it just becomes one of those things as ubiquitous as Wi-Fi
I think you can look at Star Trek as a fairly grounded example of where current LLMs could go: the ship's computer is not autonomous in any way but it does accept fairly vague instructions and you can apparently vibe-code the holodeck.
Hyperion has a pretty well-developed view of AGI.
Deus Ex is an outlier, AI is a core part of that plot
The first Cyberpunk book, Neuromancer, has a plot which revolves around A.I recruiting human agents to forward its plans...
