Importantly, though, humans evolved to live in environments full of random dirt microbes. We didn't really evolve to deal with repeated respiratory infections. Spillovers from wild animals would happen and kill a bunch of people from

Safety stops are much more challenging in a robot that tends to fall over without active balancing. Though with ISO 25785-1 in progress maybe there'll be a workable humanoid robot safety standard in a few years.

There are two separate issues here. Can an x86 be made nearly as efficient as an ARM chip with unbounded effort? Sure. But it's a lot easier to make a competent ARM design than a competent x86 design because there's so much mor

Also, even if we lacked the data to proceed with Chinchilla-optimal scaling that wouldn't be the same as being unable to proceed with scaling, it would just require larger models and more flops than we would prefer.

A modern CPU should be able to detect temperature excursions and bring itself to a safe halt even if you power it up without any cooler attached. It's normal and expected that people making mistakes around the cooling systems of their

Solar prices are coming down quite fast, I don't think a factor of two is going to be a killer here if the storage is cheap and long-lasting enough. Some people are already considering over-provisioning solar panels relative to availa

SIMD is quite old but the changes Nvidia made to call it SIMT and that they used as an excuse to call their vector lanes "cores" are quite a bit newer.

One important thing the US could have done to get the Japanese to surrender without dropping the bomb would have been to promise that Japan would not be turned into a republic after the war but allowed to keep its imperial family as ceremon

Traditionally it was ads that contributed most of the money a newspaper took in, but the fact that people were paying for the paper re-assured the people buying the ads that the papers were actually being read.

I'm getting this from the book Why We Sleep by Matthew Walker. There were some other exaggerations in the book that people have noted, though, so maybe I was too trusting of this particular fact.

Could this be an explanation for why people who go without sleep for long enough eventually just die? The Guinness Book of World Records doesn't accept records on staying awake for the same reason they don't accept records for th

This seems like a plausible evolutionary reason for sleep to start existing but humans use sleep for plenty of things besides this, like moving declarative memories form short to long term memory in spindle sleep or consolidating procedural

In practice force sensing is more useful than proprioception in most cases, at least for grasping. Generally you won't the dimensions of an object you're attempting to grasp anywhere near as well as you would know the shape of th

Are you planning on having these robots work collaboratively alongside humans? Or something more complicated like only driving near humans to start with but digging near them being a longer term goal?

I was thinking that too. There are many cases where you do want to manage memory yourself, and in that case you should likely use Rust or maybe Zig if you can choose your own tool. But if you don't want to manage your own memory Nim

That's twice the number Valve reports for Steam users which includes a lot of Steam Decks that come with Linux installed, so it seems high, I would have guessed somewhere in the 1 to 2 percent range. In some countries you have mass Li

Nah, to keep extracting the Earth's rotational energy that fast through tidal means we'll have had to import all the available liquid water from the rest of the solar system, rendering the climate change effects of the other energ

I think if we're positing a world where our energy use increases 2% annually for a thousand years and that tidal power will remain a fixed fraction of that we're not dealing with a reasonable projection. In any event, at the end

Electromigration tends to get worse with small sizes but also higher voltage and temperatures. I could see a GPU wearing out that quickly if it were overclocked enough, but stock consumer GPUs will last much longer than that.

That's a common misconception. Moore's 1965 paper was about economics but when the phrase "Moore's Law was coined in 1975 it was referring to Dennard Scaling as a whole. https://hopefullyintersting.blogspot.c
