keenmaster··on BMW EV achieves 1000km in range using Dual-Chemistry batteries
True, but the difference here is that the second battery isn’t even used most of the time, and if it was it would die quickly.
keenmaster··on Innovative wireless light switch could cut house wiring costs in half
I had a Philips Hue switch that works like that. It worked perfectly but it’s not aesthetic (chunky, clicky, and oddly shaped), so it’s for bachelors only. Lol
keenmaster··on Innovative wireless light switch could cut house wiring costs in half
Sure, but it’s compatible with smart devices without any jerry-rigging for backward compatibility, not to mention labor savings. You can probably use the transmitter to power other low energy IOT devices too.

You need more LFP to carry the weight of the manganese battery though (increasing cost), and all the extra weight can affect driving dynamics. Maybe both the cost and weight increase are minimal but that’s what came to mind. It’s a great idea though.
keenmaster··on Ban of the printing press led to the decline of the Ottoman Empire
The printing press was banned as a cynical ploy by Ottoman rulers to suppress the Arab peoples. They knew this would reduce innovation, which Arabs were adept at - maybe even reduce Arab innovation for centuries - but hey, you can’t make an omelette without cracking some eggs right?

Ottomans wrote the whole playbook for Middle Eastern dictators: systematically favor the ethnoreligious groups you like, ensure that any big business opportunities are channeled through them, and then for disfavored ethnoreligious groups, suppress avenues to wealth which can be used against their rulers. Then, with the massive vacuum of intelligence left behind as a result of this policy, let fundamentalists misuse religion in such a way to keep your opponents simple and stupid (whereas during the Islamic Golden Age, scientists were inspired by Islam to make groundbreaking discoveries, and they in turn helped spark the Enlightenment in Europe).

keenmaster··on Please don't use AI to get on the global leaderboard
Maybe Internet cafes will become more of a thing again. The manager will verify you as a real human using their computers, and the Internet cafe itself gets audited.

Or imagine a Costco Metaverse Verification Center. You can play in a VR metaverse with other verified humans at other Costcos around the world. AR cameras on the headset will ensure you can see your $1.50 hotdog and soda combo so you never have to leave the metaverse. Costco would also provide you a sleep pod at cost if you want to plug back into the matrix right after waking up.

keenmaster··on Early-life stress changes more genes in the brain than a head injury in rats
It’s not different, the two are tied. See my comments above, including my response to you related to epigenetic changes from stress.

The person you are responding to likely has notable epigenetic modifications that have lasted way past the initial negative environmental stimuli (in proportion to the trauma). It’s not a hopeless situation, there is literature on how to reverse and mitigate that, but it’s important to be aware of.

See the following study in Nature and scroll down to “Epigenetic reprogramming by ELS: the current landscape” -it gives an overview with citations and links included:https://www.nature.com/articles/s41398-022-02076-9

Telomere Effect also goes into epigenetic changes but isn’t solely focused on stress

keenmaster··on Early-life stress changes more genes in the brain than a head injury in rats
I went down a rabbit hole about this while reading The Telomere Effect (recommended reading). The book goes into the good stress vs. bad stress paradigm and how it has a biological basis - literally at the RNA level. There’s a Goldilocks zone where, for example, the right amount of good stress actually increases your lifespan, and the lack thereof is actually bad for you. Of course bad stress is bad in any amount, with bigger consequences if you’re younger or, get this, in the womb. If a pregnant woman experiences a traumatic event or bad or chronic stress, that can result in lifelong issues for the kid. I don’t recall if the book went beyond RNA and into the neuroscience aspect or whether that was from further reading, but the neurological effects are significant too.

Absolutely not. If your brain is molded in a stressful environment, it’ll optimize for reaction to and preemption of threats, with all the anti-social behavior that entails, rather than creativity, cooperation, high-level learning, and constructive pro-social behaviors.
keenmaster··on Food and Generative AI
“Burden for the user” - why not make this a burden for the AI instead? Have the AI do some web-crawling.
keenmaster··on OpenAI is exploring making its own AI chips
They won’t have trouble getting capital. It’s open checkbooks for them all around.
keenmaster··on OpenAI is exploring making its own AI chips
I bet OpenAI is trying to figure out how to have self-improving AI which suggests modifications to the hardware that runs it. You’d need some hardware expertise in-house for that (in addition to software of course), though not necessarily a big chip company.
keenmaster··on LLMs confabulate not hallucinate
There are topics where GPT-4 is more likely to be right than wrong. So when it is occasionally wrong and you happen to know to correct it, it has a more correct foundation upon which to provide further answers. This only really works when you already have expertise on the topic and use GPT-4 for inspiration and to work more quickly.

Totally agreed, “American” is interchangeable here
keenmaster··on Are the Longevity Benefits of Acarbose Rooted in Its Role on the Gut Microbiota?
I’m sure diet also plays a role. I want a tool where I can ask “if an American man is not obese, doesn’t smoke/do drugs/drink alcohol, and is not predisposed to violent early death, what is the average lifespan for people with his characteristics?”
keenmaster··on AI and the End of Programming
I actually agree when it comes to vehicles. I personally would not use self-driving until it is further refined. On the other hand, I haven’t seen LLMs used in safety critical applications or otherwise dangerous integration of LLMs into a product or service. There is mostly upside with little downside.
keenmaster··on AI and the End of Programming
True, but there is a wide range of use-cases where “failure” of an LLM is tolerated, and it’s almost never safety-critical like driving is.
keenmaster··on Diamonds are losing their allure
You’re dunking on a fictional hyper-woke straw man in response to someone sharing a wholesome anecdote about doing something nice for their wife. Lol.
keenmaster··on AI and the End of Programming
Consider that this is just the beginning for LLMs, and GPT-4 is already somewhat magical. There’s no reason to believe that this already magical program can’t get exponentially better. Magic ^ X

It’s going to be a wild ride. Also consider that LLMs don’t have the “last 5%” problem that self-driving software has, where widespread use is currently untenable because humans still need to intervene and that poses safety problems. LLMs are very complimentary to a large breadth of human work, until they stop being complimentary and instead become a substitute.

Another thing I’ll say is, the investment in the already mind-blowing LLMs like GPT-4 is relatively puny, a fraction of the cost of building 1 skyscraper. What’s happening is that the market has been validated and much larger sums of $$$ are going to flood in, including into the research pipeline which can solve problems such as data “scarcity” for future AI.

Imagine a much smarter version of GPT-4, except constantly thinking like a human does (as opposed to prompt-response-wait-prompt-response…), constantly working towards some specified goal, and…placed in a robot body like those made by Boston Dynamics. That’s not even in the far future. It’s technically possible in 6-12 months.

Finally, looping back to self-driving - I think you’ve reached your conclusion too early there. Once the last 5% problem is solved for self-driving, it will be solved for everyone and forever and getting from point A to B on the road will forever be available to you by a robot chauffeur 24/7, forever deliver things to you autonomously, and improve supply chain/logistics by a lot, with downstream reduction in the price of delivered goods.

keenmaster··on The Sight and Sound “Greatest Films of All Time“ poll
I was going to expand on this point. “Moving images” abstracts away a lot of large improvements in both the technology for producing and for consuming movies. Same with “interactive electronic entertainment” for video games. And the more limited technology in 1941 placed constraints on storytelling such that, if Citizen Kane was made today instead of 1941, just with better resolution and color (but the same shots, same dialogue, same story), it probably wouldn’t even be in consideration for GOAT by most movie critics.

In contrast if LOTR (the book series) was released today instead of 1954-1955, it would have a serious chance at being a mega best seller. It’s such a good read independent of its influence on subsequent fantasy novels.

keenmaster··on The Sight and Sound “Greatest Films of All Time“ poll
Crime and Punishment, The Picture of Dorian Gray, Frankenstein, Lord of the Rings, 1984, The Great Gatsby, The Chronicles of Narnia, and Odyssey (by Homer) are all books that I enjoyed that are varying degrees of old. I think comparing old vs new books is fundamentally different from old vs new movies. Let’s bring in another form of media since you brought up books: what about video games? Most gamers have some cutoff before which they either generally don’t play games older than that or they do but wouldn’t call any of them “greatest of all time.” This is not a deliberate decision, but a product of revealed preference. Even then, newest doesn’t mean good.

I think Morrowind, Ocarina of Time, and FF7 are GOATed, but I also don’t go out of my way to play older 2D games and certainly would never call them the greatest. On top of that, I have to admit that the games I mentioned are less enjoyable today than they were back then, and are on the same level as other 10/10s that I played in more recent times.

The medium by which books are conveyed hasn’t really changed meaningfully (holding fixed what is being written about). They’re still words. That’s not true of movies and video games.

keenmaster··on The Sight and Sound “Greatest Films of All Time“ poll
Agreed. Citizen Kane was insanely boring even though it’s supposed to be the best movie ever. I need to pull a Wittgenstein and ask: what does the word “best” mean here?

I care mostly about movies that are incredible to me now in 2023. That informs my definition of “best movies”. I am not interested in Citizen Kane’s innovative use of the deep focus technique. I can appreciate an incredible older movie, but not for obscure film buff reasons. If anyone knows of a good best movie list that is free of this sort of pretentious navel gazing, please link it below.

Also, this is a hot take, but at a certain point older movies become worse precisely because of their datedness rather than “more interesting due to what they achieved within their technological boundaries at the time”. If they’re still good, that’s because they have an absolutely stellar story.

Yep, and that is what’s going away. BMW recently decided to stop offering heated seat subscriptions.

keenmaster··on A Journey Through Spain’s Islamic History
I don’t see how this is supposed to be meaningful. Ancient Greece was incredible for its time, and modern Greece is relative poor. I hope we both agree that doesn’t diminish Greece’s past in any way.
keenmaster··on A Journey Through Spain’s Islamic History
Janissaries were a uniquely Ottoman practice, and evoke something completely different than Muslim Andalucia. Also, I don’t believe that the Ottomans mutilated Janissaries in the way you described - that would be counterproductive, since strength is important in the military, especially with highly motivated elite soldiers. Look it up, that’s a popular myth, no more real than the Unsullied in Game of Thrones.

In contrast to the Ottoman Empire, no one talks about some great Andalusian army. Al-Andalus was known for its culture, architecture, scientific innovation, multiculturalism, etc…that being said, the American school system doesn’t really cover Al-Andalus, the so-called Islamic Golden Age, and Muslim advancement of the frontier of knowledge.

keenmaster··on Reasons to replace advanced search with filters
Lol. I should have said AI rather than LLM because it would look at product images too - GPT-4 is already multi-modal. GPT-5 (and equivalents) is probably where services like this will start trickling out, and by then the model should have a lower error rate. The jump from 3.5 to 4 was huge.

The AI doesn’t need to be perfect - even if it makes an occasional error such as showing you a couch with flame retardants, you can spot that in the listing yourself. Most other qualities of a couch are very visible and you’ll be able to tell visually how good of a job the AI is doing.
