<p>I have done a fair amount of low level performance optimization with Opus 5 and its reasoning is still very poor. Like why is CRC so slow and going through loops until I ask it if is using hardware instructions and it tells me it is using its own hand coded implementation poor. Reasoning about l1/l2/l3 cache hit ratios and their implications basically throwing darts at the wall, in the wrong room. If you give it a benchmark feedback loop then it might get there eventually but still massive alpha for low level systems engineers who instinctively know how this stuff works and can now automate 99% of the grind.</p>

<p>Wrong. Have you read your agents TOS? You run the agent, you accept all responsibility for what it does. You are free to sue Anthropic to try and get your money back but you already indemnified them of liability, so good luck.</p>

<p>No, application of the principal of respondeat superior would most likely be applied to an AI agent the same as a human employee. An employer is held responsible for the actions of an employee even if it is clearly contrary to their intentions.</p>

<p>In a civil contractual dispute you can only recover actual damages. If the contract was sent, and the other party performed work on it that had a cost for them, then most likely, yes, they would be awarded damages if you refused to compensate them for any costs incurred prior to notification that the acceptance had been sent in error.<p>The other outcome would be clearly inequitable: forcing the counter party to eat the loss for your irresponsible use of an AI agent.</p>

<p>And I don't want to read the millionth iteration of some old man complaining about the kids these days, written by a human or not, yet here we are.<p>If you don't like AI slop. Don't read it. But wasting your time generating human slop to complain about AI slop is so obviously futile that it immediately identifies the writer as lacking the capacity for reason or emotional clarity, or merely seeking attention for their self-promotion with clickbait.</p>

<p>LLMs are just one small part of computing. it is fine to learn how they work but they are nothing magical. if you want to build a real working system using LLMs that actually makes money you still have to learn everything else. but i think his point here is that learning LLMs at 17 means hacking together some home brew rig on shitty consumer hardware and if you learn all of that you will be in a much better place than learning how to use chatgpt to automate a spam campaign for your b2b saas startup.</p>

<p>llms are 100X for me, but only 10X goes into actual shipping code. the rest is all on doing the dev process the way it actually should be done: incremental POCs, refining specifications, modularization, exhaustive test suites with 95%+ logical unit test coverage, fuzzing unit test coverage, exhaustive e2e testing, with a fuzzer harness over e2e tests for long term simulation and scale testing, bechmark gated self improvement loops for performance optimization, etc. i guarantee you i can ship higher quality 100% llm generated code than any human.</p>

<p>I have used AI almost exclusively for a year, but I was programming by hand for almost 30 years before that. I don't think there is any difference between going from assembly -> C -> Java, TypeScript, C#, Go, etc, and taking the next step to AI. It is just another intermediate abstraction layer that allows you to work at larger scale.<p>Programming with AI enforces some good disciplines, which were always true, but could be avoided doing it by hand. Most importantly: you are shipping your tests. If you don't have reproducible automated tests then it probably doesn't work.</p>

<p>The problem is that the cost curve for completeness/correctness goes asymptotic at 90-99% so the cost up building complete/correct software is never worth it from a revenue perspective, and only happens if there is significant liability risk from defects.</p>

<p>The concepts of industrial reserve capacity and using dual-use consumer goods to subsidize military production capacity are well known and widely practiced historically in the US. China adopted this strategy from the US, and the US conveniently forgot about it for a few decades in order to justify selling off the industrial base to China, but at least based on public documents like the published U.S. National Security Strategy, I would assess with high probability that this is explicitly recognized and being followed now.<p>AI is not fake and it does work, but what I am saying is that from a pure systemic analysis perspective, you can do the numbers, and even if AI was complete fugazi, the benefits you get from the electrical generation capacity, and the ability to fund it through private markets, which bypasses Congress, and locks in commercial contracts (often with foreign governments) which will be almost impossible politically to reverse, would still make it optimal from a strategic perspective. That is my calculation, and to the extent that it is correct, I would assume that the US Military's strategic planning apparatus would arrive at the same conclusion.<p>AI compute has some unique characteristics that make it especially useful for grid management. Moving consumer compute to the cloud means that the electrical use of that compute can be centrally managed. In an emergency, you can cut electrical use for consumer AI by 50% or more, because chips run more efficiently at lower power, and you can shift workloads onto quantized models, reduce resolution for video output, etc, to reduce compute, which leads to minor service degradation but not interruption. AI datacenters are also adding massive amounts of battery storage capacity, which is an additional grid buffer. For every GW in capacity added by hyperscalers that is creating a dispatchable reserve capacity of 50% under completely normal circumstances (hyperscalers do this internally to optimize their own costs) and then that number goes up depending on the scale and duration of the emergency.</p>

<p>This also comes with significant capability reduction. deepseek-v4-flash is very good in the < 250K range, then degrades between 250-500K, and is practically unusable after 500K.<p>[edit]<p>This is my observation from using it without an specific context engineering to optimize for Deepseek's cache compression and sparse attention mechanisms. I am pretty sure that if you specifically structure your context to align to the cache compression boundaries you can significantly improve performance in the full 1M context, but there is not much reason to do this, because if you design your outer loop to work with shorter contexts that solution is portable and more efficient, so I haven't bothered with a optimizing for DS at this point.</p>

<p>Deepseek is still charging cached input at 1/10th the price of any competitor.<p>For an example of my real token usage for a day with DS: Input (Cache hit) 530,949,760, Input (Cache miss) 7,875,004, Output 1,389,685 - it is still 1/5th the price of Baidu (the cheapest) and 1/7th-1/10th the price of US hosts.<p>Also, Deepseek platform is not the same thing as Deepseek open weights. There is a major misconception that the existence of an open weights model means that it is the same thing as the proprietary platform offering, but that is definitely not the case.</p>

<p>You really have to look at energy/capita and how much energy is embedded in exports. The gross numbers are misleading. The US wasn't building new electrical generation capacity because it didn't need it and there was no market for it (caveats apply, but in a broad sense this is the major reason). Now that the market exists the question is how much can the US actually bring online and how rapidly, which is a real challenge after decades of degrowth politics used to justify slash and burn consumption of the industrial base.<p>AI is really all about electricity. AI could be completely fake and yield zero value whatsoever and the US would do exactly what it is doing now because the AI bubble is what creates the market for building new electrical generation capacity, which is needed for re-industrialization. Also why our friends in UK/Europe/China are so busy pushing anti-AI propaganda to try to undermine this.</p>

<p>I don't disagree but something less bad is better than something more bad if those are the only two options. I only said Duolingo was better than Youtube. Duolingo is nuts. I get my children's spam from them and it is this crazy emotionally abusive manipulative therapy talk nonsense trying to get them to use the app. I hope they are using AI to write that. LOL. I can't imagine the actual human who would do that for a job.</p>

<p>Can you point to any serious studies that show the opposite? No. They don't exist. There cannot be any serious studies until there is a generational cohort that can be evaluated for long term impact.<p>But on a personal level I would vastly prefer my children use even a crappy AI chat app like Deepseek than watch Youtube. If you have young children and pay attention it would be almost impossible to come to a different conclusion.</p>

<p>literacy causes profound brain structure changes and psychological effects, and mass literacy results in profound social transformation. which is why people have be trying to prevent the spread of literacy for thousands of years, to this very day.<p>an LLM is a next token prediction function. of course it matters how you use it, and if you want to use it for an educational purpose, that has to be intentional, so i agree with you on that.<p>chatgpt and all the other ai powered scams and attention monetization apps are horrible, because they are just using improved technology to accelerate the exploitation of consumers (both adults and children) of media and app platforms.<p>the solution here is not to say the technology is bad but to use it to create competitive products that are actually beneficial.</p>
