This article starts off well enough and covers some things I had been thinking about myself: exploring the many-dimensional space of an LLM. But then I think it veers into good old human hallucination (buzz-words disconnected from realities).

It even mentions my favorite show "Connections," but gets it wrong: it wasn't showing obscure or unlikely ideas, it was highlighting under-appreciated historical paths of developmnent. The one I remember (and have seen repeated on youtube since) was how the lathe boot-strapped the industrial revolution, crude ones at first helping to build more accurate replacements for themselves.

I want to give the author some credit for exploring some of the new possibilities that the LLM constructs offer. But the second half just veers into unreal territory. Typically, the author takes the words "latent space" and divorces them from their actual meaning to just make up stuff.

"Retro latents": nobody except historians will want to revisit the uncanny valley.

"simulate all possible latent spaces": that's just n-dimentional random matrices, for n trending to infinity, computationally infeasible. "computationally sweep through the space of all possible latent spaces, in a sense mapping the nature of latent space itself": no for the same reason. A "latent space" is only significant because it is based on a reality. It makes no sense to us to make a random "latent space" and ask what reality that corresponds to.

"create simulations of various propositions by moving through the latent space": there was already a documentary about this, it was called "The Matrix."

"Latent spaces contain all parallel worlds": if properly constructed and queried, it seems they would really only contain our reality. A parallel world would be a different "latent space" (ie big matrix) with different values.

The "Personal latent space" does make me think there might finally be a way to "download" our brains into silicon, but you'd really have to train it with google glasses running 24/7 from birth, and nobody wants that. Plus, it would be a security nightmare: unless you could carefully guard all access in an air-gapped container only you control (a bit like your brain in your body), you could be duplicated and your virtual duplicate could drain your bank accounts, be easily blackmailed, steal your IP, etc.

Just like planting trees, the second best time is now. Travel (with sensitivity and understanding) to see cultures and places that are at risk: glaciers, savanna, wildlife parks, minority cultures, and dare I add Western democracies.

Edited to add: maybe the computer history museum as well.

I hope that pun was intended‽

Also note that due to isotope decay in the ore, a natural reactor is no longer possible. From the wikipedia article:

"A key factor that made the reaction possible was that, at the time the reactor went critical 1.7 billion years ago, the fissile isotope 235U made up about 3.1% of the natural uranium, which is comparable to the amount used in some of today's reactors. [...] the current abundance of 235U in natural uranium is only 0.72%. A natural nuclear reactor is therefore no longer possible on Earth without heavy water or graphite."

Another fascinating detail from the article, due to our understanding of fission, we can get some incredible results:

"The concentrations of xenon isotopes, found trapped in mineral formations 2 billion years later, make it possible to calculate the specific time intervals of reactor operation: approximately 30 minutes of criticality followed by 2 hours and 30 minutes of cooling down"

hacker news really needs a best-of page the way craigslist did (sorry, does), just so I can nominate this. Made me discover a great song (and a great cover), with such a wry commentary (the song's and your own comment being spot on for the original drivel). Or like we used to say, you win the internet for today.

The island of Kaua'i in Hawaii has both tours of a chocolate farm (Lydgate Farms) and a coffee plantation (Kaua'i Coffee) with a visitor center. Just gotta find a conference out there, then hop on a Southwest flight.

As others have mentioned, Teslas charge at their fast chargers (and getting faster all the time) spread around the area. Other cars can do the same, or at workplaces. Some new building codes now mandate that the parking be charging ready, so they have to put the conduit under the pavement, but they don’t need to wire it right away. So that’s a first step to simplifying a retro-install.

I do think apartment parking will eventually be retrofitted. The charging networks could easily have a apartment product—or license their network access to a manufacturer. So you would just use your charging network app or card as when charging around town. There are also products like Evercharge that split the power from a single circuit across several plugged in cars (optimizing power usage and reducing the need for conduits and wiring).

The various EV promoters have been tackling this issue for a while, something like the Electric Auto Association may have people or resources to help convince an apartment owner.

I wonder: shouldn’t a grid with lots of solar incentivize workplace charging (day-time use of peak generation), and a grid with wind majority incentivize home charging (night-time use of peak generation)? Maybe

I remember reading Sun’s financial statements at the time and bragging about huge 50% margins and thinking that can’t last. In some alternate timeline, Sun would’ve lowered their prices, stayed in the game, and we’d all have rock solid Sparc laptops by now.

I remember that company towns had to allow private speech, but I never heard that shopping malls had to. I always thought that any protest or disruption or unpopular speech in a mall would get you escorted out by security.
