I can understand your stance if you think that AI is just a fad. But for those who believe that AI is going to kick off a new industrial revolution, it's the difference between that new industrial revolution being in the hands of people like Musk and Altman (who are profiting off of having scraped the commons), vs. the public as a whole.

Prompt:

Hey ChatGPT, who is being reasonable in this argument?

---
Rei: " ... We think of bees as mindless drones (literally, we took the very word!), but they're all individuals each acting on their own.... "

Synonymous Homonym: "Drones are specifically the male bees. Most bees are not drones."

Rei: "That's not what I said. I said that the word "drone", as in a mindless unthinking being, is derived from drones, as in male bees. I did not say "all bees are drone bees"."

Synonymous Homonym: "What you actually said:

We think of bees as mindless drones (literally, we took the very word!)

Suggesting that the word "drone" means "mindless bee.""

Response:

Rei is being more reasonable here.

The key issue is whether Rei's original sentence implied that all bees are drones or that "drone" as a metaphor comes from bees.

Rei wrote:

"We think of bees as mindless drones (literally, we took the very word!)"

The parenthetical "literally, we took the very word!" naturally reads as:

The figurative word drone (meaning a repetitive, unthinking worker) comes from the bee term drone.
Therefore, our cultural association of bees with "dronelike" behavior is reflected in language.

That is a claim about etymology, not about bee taxonomy.

Synonymous Homonym's first correction:

"Drones are specifically the male bees. Most bees are not drones."

is technically true, but it doesn't actually address what Rei was saying. Rei wasn't claiming that all bees are male drones.

Then Synonymous Homonym shifts to:

"Suggesting that the word 'drone' means 'mindless bee.'"

This doesn't accurately paraphrase Rei either. Rei never said the word means "mindless bee." The sentence only suggests that the metaphorical sense of "drone" is derived from the bee term.

If I were judging the exchange, I'd say:

Synonymous Homonym's factual statement is correct: drones are male bees.
But it's responding to a claim Rei didn't make, making it a misreading.
Rei's clarification directly matches the ordinary reading of the original sentence.

So the stronger interpretation is that Synonymous Homonym misunderstood the original remark, and Rei's correction is justified.

Or to put it more simply: you're attacking a straw man (a claim I never made) because you cannot defend your actual scientifically inaccurate comments about bees having half-hour memories.

You are confusing "forgetting" with "disruption".

I am not.

Your entire argument was that bees have short-term memories. The example you cited demonstrates precisely the opposite - that bee memory is if anything too durable>/i>, such that bees will refuse won't even bother searching for their hive if it has been moved, that they always go back to the spot where they remember it being last.

However, what you are choosing to ignore is that, once a bee has been accepted into a different hive, it becomes part of that hive

That's like claiming that if you move to a different city, you've "forgotten" where you used to live.

When a bee, due to a navigation error or its previous hive being gone, enters a different hive (drifting), it absorbs the pheromones of the new hive. It is now chemically marked as belonging to that hive. Chemicals are communication to bees, just as much as vocal commands are to you. Bees do not learn all of the other bees in their hive, they don't have some sort of rolodex. If you smell like hive A, you're allowed into hive A. If you smell like hive B, you're allowed into hive B. Bees don't particularly "care" which hive they're in; they have their own individual motives and drives, which simply involve being in "a" hive. Once they're marked as belonging to hive B, they can no longer enter hive A (at least not safely).

Note in the above what has nothing to do with any of this? Memory. It's just about smell. Memory is about where the hive can be found after foraging (which is also about memory) - and it remains, even after drifting (they'll continue to return to the same spot - again, even if the new hive is moved). Smell is about which hive you can enter. Or for a summary version:

1) A bee leaves the hive to go foraging

2) It remembers where the best spot to visit is (usually from having gone there before, but occasionally from having seen a waggle dance) and what flowers (shapes, smells, sizes, etc) will be yielding best there at what times of day, and what areas to NOT go to, where there may be threats. This information persists for days, weeks, or even the bee's entire life. It can target an area to an accuracy of a couple hundred meters, and then begins a search.

3) When done, it returns back to where it remembers that the hive should be (this memory is highly persistent, and can only be reset by an orientation flight.

4) The bee starts by using the sun and broad navigational features as with outbound flights to get to within a couple hundred to a few dozen meters (the "visual catchment area"), then gradually switches to small-scale features and searching. This is all based on memory.

5) For the final approach, the bee relies on a mix of sight (remembered), sound (generic), and smell. The latter is not a learned trait, it's "whatever you happen to smell like". While it's usually described as recognizing the smell of their sisters, that's not exactly right. The actual underlying mechanism not so much learning what something does smell like as it being unable to detect what they do smell like

The mechanism the same as how humans become unable to notice their own body odour or perfume: sensory adaptation. Because they're constantly smelling themselves, their brain learns to tune out their own smell. However, it doesn't tune out the smells of others. When they return to their own hive, the scent is something that they're adapted to tune out. But when they arrive at a different hive, they're hit with a scent that they're not adapted to, and that they can detect.

If you want to put it in human terms, the underlying mechanism is "this hive thinks you're stinky, that one doesn't smell you because you've all been around each other for so long".

If you want to call sensory adaptation "forgetting", then you're going to need to call human sensory adaptation "forgetting" as well. And again, none of this has anything to do with actual memory tasks, such as navigation and how to find the best flowers. Bee memory is exceptional with them.

You might want to read up on how current hybrid vehicles actually work, 'cause it seems you have more than one misconception going on.

I have. For instance, my latest vehicle is the Ford F-159 XLT,, the full-hybrid model of the F-series pickup truck line. Power train is:
  - 6 cylinder dual-turbo engine. (runs low power but approoximately doubles output when a lot is needed.)
  - 47 HP motor-generator "pancake" on the engine side of the ttransmission, to scavenge / return power to./from a 1.5 kWhr lithium battery.
  - 10-speed automatic transmission, working with the lithium battery;s main alternator to fine-tune match the engine/mogen to the current driving situation. Max power of engine plus hybrid mogen; 430 hp.
  - full four wheel drive.

So it's primarily a gas-engine power train with an electric-car motor mechanically coupled to the engine shaft. Many other hybrids, from the venerable prius onward, are similar, with plug-in variants having a big scavaging/peaking battery good for pure electric operation of tens of miles rather than a minute or so and a wall-powered charger added.

What I'm looking for is essentially a pure electric - totally electronic "transmission" consisting of alternator(s) between the batteries and the motor(s), plus a tiny engine-generator able to burn gas and feed some teens of KW of charging power into the batteries when running down the road or parked near it.

So in other words, they want to offload their failing businesses onto the US Taxpayers.

That's not really the point.

The point is the upcoming revolution in autonomous labor, which will turn our current financial system upside down.

For reference, you might want to check out Manna, by Marshall Brain (his actual name). It's an easy read, it's short, and it outlines the impact that robot labor will have on our current model of capitalism.

It's no secret that ChatGPT is useful, and a force multiplier for productive output. If that type of breakthrough can be achieved with physical processing, then much of the labor force can be replaced by robots.

The current economic structure assumes infinite consumption, that there will always be more people (rising population), and that they will always want more things. We've found out that the first part isn't true, and it seems that the second part isn't true either: once you have "enough" stuff to have a comfortable life, many people stop consuming and turn their efforts to other things. People aged 45 to 55 spend the most money (per household), but once they have accrued a level of comfort they stop and enjoy life.

If robots can do manual labor, then that will put most people out of a job. A robot factory 20 miles on a side out in the southwest US (a thought problem for discussion) could supply the material wealth of the entire nation, but only require 100,000 human workers for management, direction, and maintenance. That figure, 100,000, is negligible compared to our current population.

How do we support the remaining 300 million population?

One way is to create an AI soverign wealth fund. Some portion of the factory output is given to the population in the form of factory currency. Each month every person would get, say, $1000 of factory currency to spend, with online ordering, and the items would be delivered.

To the article's point, we know with certainty that our current economic system will transition into the factory robot model. The problem facing economists is how to transition us into that model without going through a catastrophic financial failure.

An AI soverign wealth fund could be the first step towards making that transition.

Comment cobalt chemistry, not so nice. (Score 1) 111

Do the Waymo batteries use one of the lithium chemistries including cobalt, or a non-cobalt chemistry such as lithium iron phosphate?

Cobalt chemistries have a higher power/weight and energy/weight ratio, which made them the go-to chemistries for vehicle batteries. But they also produce oxygen when the cells overheat, leading to an unextinguishable runaway fire hazard: A burning cell makes enough heat to ignite the adjacent cells, so the whole assembly of them goes. Bad enough when it's a car's worth, but a disaster if it's a shipping-container sized module of a utility energy storage site. (And even worse when the site is a building full of racks, which someone had "protected" from fire with water-spraying, equipment-shorting system, so the whole site burns up, as happened recently with one in California creating a toxic mess.)

That's why purpose-built stationary lithium energy systems use non-cobalt chemistries - heavier, but a shorted cell just kills itself without getting hot enough to light off its neighbors.

I want to see inexpensive plugin hybrids.

But not like the current ones, which are primarily an engine/tranny powertrain with a motor/generator + small battery for scavenging downhill/braking energy for later accelleration/uphill/cruise/power-boost.

I want ones that are primarily a battery-electric with a small aux engine-generator (say 15-20 HP range), big enough to power crusing with a bit left over for gradually charging. That would let you range-extend by the size of your gas tank plus fillups (i.e. indefinitely if only gas is available) or go from battery empty to back on the road in a couple tens of minutes.

The backup engine would only run at max-efficiency speed and could use an atkins-like cycle (see "liquid piston engine") to get the max power out of the fuel. Most operation would use power-grid charging (when available and cheaper than fuel).

Bluesky knows full well it's not operating a real federated service

Better tell that to Blacksky, Eurosky, etc.

The vast majority of people stay on the primary PDS, relay, etc namely because Bluesky hasn't proven itself to be some evil overlord pursuing insidious goals. If that were to ever occur, people would just migrate. Unlike with ActivityPub (Mastodon), ATProto allows for true migration. Your content isn't tied and linked to a specific server - it's more like a URL on an arbitrary domain, and you can just change the "domain" (the PDS). Everything is timestamped and cryptographically signed, so if you download a backup of your content, you can just reupload it somewhere else and it continues to remain linked into the whole ecosystem.

More to the point, primary Bluesky servers have gone down and third parties like Blacksky remained operational, very much demonstrating that the network is federated.

Also, re: this from the header:

" and by the end of October last year, it had reportedly seen a 40% drop in daily mobile active users over the past 12 months."

... is cherry picking. If you graph users, you'll see that - like most sites - new users tend to arrive in big "spikes", triggered either by events at other social media platforms, or major news cycles (such as elections). Most new users to a site are not "sticky". Some drop off in days, some in weeks, some in months, etc, but this slowly levels out, and the rest are "sticky". With Bluesky, usually half or so of new users stick around, which is an unusually high percentage. If you measure from a new-arrivals spike, of course you see a "dropoff", but you see that for any site. The question is, how is the long-term trend of users that stick around? If you cancel out the spike pattern, Bluesky has a long-term population of around 600k daily posters / 1M daily likers / 300k daily followers.

What you can say is there haven't been any big new user spikes since late 2024 / early 2025. That said, there kinda was some serious news going on in late 2024 / early 2025....
