I use codex daily and a moderately complex plan + a few files is more than enough context to make it blatantly ignore prompts like "stop and ask before adding new layers or data structures"

> Just look at how hard it's been to protest all the new gas plants that came up over the last ~20 years.

People have been talking about SMRs being the economic future for over 70 years. It has not happened because it not true.

And a contrasting article from IEEE: https://spectrum.ieee.org/the-forgotten-history-of-small-nuc...

> Samuel B. Morris, the general manager and chief engineer of Los Angeles’s Department of Water and Power, traveled all the way to Geneva in 1955 to attend the first International Conference on the Peaceful Uses of Atomic Energy. There, he made a case for small reactors, arguing that because the “number of small units…is many times the number of large units,” there could be “economy in development and repetitive manufacture” of the small units.

> But nothing in the history of small nuclear reactors suggests that they would be more economical than full-size ones. In fact, the record is pretty clear: Without exception, small reactors cost too much for the little electricity they produced, the result of both their low output and their poor performance.

For me, SMRs don't pass the smell test. Buying one big plot of land for a reactor, building one power interconnect, having a localized water impact is way easier and cheaper than many. Even if its cheaper to build small reactor vessels, MANY of the other costs become more expensive in larger numbers. Costs that you can ignore while you're just building a prototype.

If it's so much cheaper to build multiple small reactors, just build one big plant with 24 small reactors. Thing is the nuclear reactor part is only 10-15% of the plants full cost: https://world-nuclear.org/information-library/economic-aspec...

1. those charges were dismissed

2. the article address that specifically:

> The case is an example of Flock cameras being used to arrest a wanted alleged criminal suspected of committing a violent crime. But it is also an example of police surveillance overreach *in that the cameras were specifically used to create a pretext to tack on additional petty crimes* based primarily on where a person’s vehicle had traveled.

dendrites are not really a significant problem in popular batteries. It's associated with lithium metal, vs lithium in normal batteries is in the form of salts. Solid state lets you use metal, which is much more energy dense since you don't need the salts.

The most common lithium battery failure mode is that you have a hole in the plastic separator between the +/- sheets inside the battery, which shorts and causes a hotspot that eventually starts a fire. Dendrites cause the short by growing across the gap. In normal batteries it is caused by a manufacturing defect. The outcome is pretty similar.

The energy "stored" in the light oil electrolyte of a battery is >10x more than the electrical energy or the energy released by reacting lithium alone.

An 18650 battery weighs ~50g and stores ~10 watt-hours. 10 watt-hours is 8,604 calories, enough to heat 50g of water by 172 C or 310 F. The battery would not even burn without a liquid electrolyte to ignite.

The time between gpt 2 and 3 was 15 months. The time between gemini robotics 1 and 2 was also 15 months: https://blog.google/products-and-platforms/products/gemini/h...

The difference between gpt 2 and 3 was insane. 2 could generate limericks when it wasn't repeating a word 300x. 3 could actually do some things. By comparison gemini robotics has hardly changed at all.

I will also point out that slow, non-fluid robotics is on a totally different level of difficulty from fast fluid motion. Asimov could walk pretty smoothly, but it didn't fall over because it used a very careful sequence that was never unbalanced; you could pause at any point without falling over. Move faster, like boston dynamics, and you need to account for the change in balance from your arms swinging... or rather, you need to be able to account for the rotational inertia etc from moving multiple masses along complex paths with multiple points of articulation at hundreds or thousands of times per second.

An algorithm to fold tshirts 90% of the time is easy. The cloth hangs down by gravity and you can just look for right angles (corners), find their coordinates with binocular matching, and move them to meet each other. Getting 99%, or folding them quickly, so that the fabric is actually moving instead of just hanging still- incredibly, incredibly more complex.

Scale obviously does not make this more okay; watching many intersections or cell towers is obviously less reasonable than a single intersection or tower.

> In comparison: license plates, when in public, are always visible, and very easy to discern from one-another (different state-unique numbers); so in my mind the expectation of privacy is far lower.

Legally, overhearing a conversation is not different. If you are loudly talking about your drug deals in public in front of an officer, they can use that as evidence. A police department could hire officers to stand everywhere in public and listen to every conversation nearby.

Or, more specifically, they could stand conspicuously close to every payphone and listen. The phones are in public; the officers don't need to be uniformed. Practically speaking this is not at all different from wiretapping. That's what the police did in Katz- wiretap a public payphone.

Flock cameras are not in any meaningful sense different from having officers follow around everyone and record everywhere they go. Its irrelevant whether one officer is following one person or if many people are following them, each within their own small area. That would absolutely not be legal without a warrant. The only difference is a private company is doing it and selling it to the police, something that should clearly not be legal.

"some caching gains" is a pretty huge understatement- snipping something out of the middle of the window requires rebuilding the entire context. Thats a shitload of tokens.

Afaik messing with the context also pretty reliably degrades performance still. The model responses reference things that no longer exist to it and it becomes more chaotic.

The real usefulness of parallel or sub-agents is not that they run at the same time, its that they isolate noisy or self-contained context away from the main window.

browsers aren't common either. Standards, formats, and interfaces are, which is exactly what WASM is and what this demonstrates. Native apps don't need a common operating system or even a common core like nix. They just need to support a common interface, like browsers do.

for me the eyes are also showing the unwrapped texture of character's own heads, which is extremely unnerving lol

Totally missing my point.

Say you have bladder pain and chatgpt tells you that is a common indicator of appendicitis. If you go to the doctor and tell them you think you have appendicitis, they will think you are saying your appendix hurts and look for causes of pain in that region. They will not look for bladder-related pain, because you did not tell them what hurts.

Extrapolate that to all the possibilities for all conditions- something that the system is not equipped for. Doctors do not know that bladder pain is a possible indicator of appendicitis because of experience or logic; they know because it is part of their education because the system has learned that over time. The system does not account for people filtering their symptoms through chatgpt.

Further, it's still bad. It still increases the permutations the doctor is required to consider for no reason. Doctors make mistakes- they make mistakes often. Knowing a bit of medicine can be very helpful for patients. Weaponizing them with a predictive text machine is not the same thing.

We have standards of care for a reason. They are the most basic requirements of testing. Ignoring them is not just being a bad doctor, its unethical treatment. Its the absolute bare minimum of a medical system.

> I do feel I actually biased the first doctors opinion with my "research."

It may feel easy to say doctors should just consider all the options. But telling them an option is worse than just biasing their thinking; they are going to interpret that as information about your symptoms.

If you feel pain in your abdomen but are only talking about your appendix, they are rightfully going to think the pain is in the region of your appendix. They are not going to treat you like you have kidney pain. How could they? If they have to treat all of your descriptions as all the things that you could be relating them to, then that information is practically useless.
