![Figure 1
Illustration of why AI systems cannot realistically scale to human cognition within the foreseeable future: (b) Human cognitive capacities (such as reasoning, communication, problem solving, learning, concept formation, planning etc.) can handle unbounded situations across many domains, ranging from simple to complex. (a) Engineers create AI systems using machine learning from human data. (d) In an attempt to approximate human cognition a lot of data is consumed. (c) Making AI systems that approximate human cognition is intractable (van Rooij, Guest, et al., 2024), i.e., the required resources (e.g. time, data) grows prohibitively fast as input domains get more complex, leading to diminishing returns. (a) Any existing AI system is
created in limited time (hours, months or years, not millennia or eons). Therefore, existing AI systems cannot realistically have the domain-general cognitive capacities that humans have.

@olivia.science They're going to compel me to do yet another paragraph by paragraph analysis. "Brilliant"! the man said.
Absolutely brilliant piece about the Left's TOTAL blindness on AI. Their dismissal of AI risks mirrors how climate deniers treat CO2.
Will probably get a lot of nastiness for this on Bluesky, but I guess that's part of the same problem.

The left is missing out on AI
As a movement, it has largely refused to engage seriously with AI, ceding debate about a threat and opportunity to the right

Indeed, and that was the academic integrity norm for ages until opportunists decided misconduct pays. Ghost authorship is well-trodden fraud and COPE has a flowchart for handling it (the crime is deceiving the audience about the author having performed the cognitive processes to write the paper).
Senior academics organizing these conferences laid the groundwork for this denial of service attack, creating explicit policies to welcome LLM-generated "papers", to normalize LLM-generated "reviews", and partnered with tech companies in PR/lobbying campaigns.
