<p>It demonstrates that current LLMs are completely unable to follow a simple series of logical tasks. I feel the same way about ARC-AGI 3. While it might be the winning approach today, if they need this amount of complexity to do something simple, then it shows that their ability to generalise is clearly limited. Mining ore in Minecraft shouldn't be such a challenge for LLMs and yet apparently it is!</p>

<p>As impressive as this is, I can't help but conclude that the need for agents to write JavaScript programs to act out their actions represents a considerable limitation in current AI reasoning.</p>

<p>My thoughts are without a doubt closer to code than writing.
Thoughts are more often than not non-linear, so putting them into writing is challenging.
Meanwhile, when I think of code—and also when I physically <i>write</i> code—it's always possible to leave holes and stubs to be filled in later.</p>

If efficiency reduces energy demands then it directly results in less carbon.<p>> electric vehicles<p>Aren't people already adopting electric vehicles? Do you think that the government should introduce a scheme to persuade people to buy electric vehicles? Does the availability of charging for electric vehicles need improving?<p>> Efficiency is good after you have high living standards but the UK should probably focus on growth first<p>Efficiency means saving money. In what circumstance could efficiency be bad? The grid responds to demand, unused electricity means higher prices for consumers. One of biggest issues right now in the UK is cost of living crisis, so raising electricity prices would be universally hated. How does making the grid less efficient increase growth?</p>

<p>I would question the narrative that humans lack the capacity to verify the output and would instead argue the people lack the incentive to verify the output.<p>The response of many mathematicians to the recent dump is a good example: verifying these proofs amounts to unpaid labour for OpenAI and wastes time that could be spent doing publishable work which ultimately results in money or personal success. The slop factor also compounds the work required to verify the output considerably.<p>For mathematicians, programmers or anyone, if the work required to deal with slop passes the limit, it is no longer in their own self interest to use LLMs. The expectation that people will use LLMs for the betterment of humanity against their own financial interest is baffling.</p>

<p>I agree. The idea that mathematical achievements by LLMs could involve plagiarism didn't seem common before but now the question can be asked of any new novel proof of construction generated by LLMs.<p>It's also notable that the Open AI proof may not even be interesting to mathematicians.<p>Even if people already had an idea that LLMs were training on user inputs, it's the first time it's actually caused an issue. Mathematicians, and plenty of researchers, working in ambitious or competitive field now have a very good reason to avoid LLMs.</p>

<p>Quite a few of the challenges revolve around asking for LLMs to complete tasks reliably and aren't about whether an instance of an LLM completing the task exists. Quite a few of the goalposts are consequently completely changed without the surrounding context, are not the same as what the HN commenter requested and hence seem disingenuous to me.</p>

<p>Being a superset of Python may not be necessary to be successful, but perhaps non-committally proposing it was necessary for Modular to win the funding they wanted. While lots of people indirectly run GPU kernels with PyTorch, I think the number of people wanting to write their own kernels is considerably smaller and that this niche already has established players (plenty of whom even already build on top of MLIR), making Mojo's most obvious use case difficult to sell.</p>

<p>I don't think the goal of being a true Python superset ever existed.<p>Given that there are so many failed attempts to optimise arbitrary Python code, it was dubious from the start. Furthermore, the documentation completely ignored these challenges and made it clear that Mojo's goal was to compile to MLIR in order to write kernels for machine learning. The first example of Mojo code was a low level matrix multiplication kernel taking advantage of fancy compilation features and the documentation advertised pointers inspired by Rust's move semantics, neither of which are typically considered friendly or relevant to high level programmers.</p>
