If they’re admitting 81 planes, drones and helicopters worth $3.3 billion have been lost in Iran, imagine what they’re not telling us. The real cost is likely far higher, and our grandchildren will be paying for this unnecessary war and his reckless spending. www.businesstoday.in/amp/world/st...

This is your occasional reminder that generative "AI" in particular could have been developed on public domain materials and/or licensed and compensated works but the major players intentionally, methodically and systemically chose to steal labor from working creative folks instead

Footnote 23 in Reclaiming AI: link.springer.com/article/10.1...
footnote 23 Similarly, no finite set of ‘impressive’ observations about AIs/LLMs
establishes that they exhibit a (human) cognitive capacity. This link can
only be theoretically established; i.e., if we propose that a machine has a
cognitive capacity X , we must also formally charactise X such that the
machine’s capacity Y can be mathematically proven to be X ≡ Y under
relevant and naturalistic conditions, using appropriate proof techniques
(see, e.g. Blokpoel & van Rooij, 2021, Chapter 5).

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. [Made with elements from freepik.com.]
