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.

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....

Their economic analysis is BS. For example, they discount the cost of "shared" infrastructure, but clearly there is a cost because it has to be built, and scaled to the number of reactors they want to install. At only 300MW each, they will want quite a few of them to make the economics better.

The increased cost of waste handling and refuelling is not properly accounted for either.

Stuff falling in is really falling quite a long way. If its path doesn't intersect the event horizon, ie, it "misses" the black hole: it either smacks (really hard) into other stuff down there that's also not quite fallen in, or slingshots back out. The event horizon being comparatively small, a lot of stuff ends up either in a very hot accretion disk around the black hole, or being blown back out in jets or winds.

This is why black holes are the hearts of some of the most energetic astrophysical objects in the universe: powered by stuff almost falling in, and all that gravitational potential energy turning to kinetic energy turning to thermal energy.

That was the original idea with numbers stations, so it was a natural evolution. Owning a consumer radio was not suspicious, so broadcasting on standard civilian frequencies made sense.

The "random" data in the GPS signal is supposedly there to aid with reception and validate the RNGs on the satellites, but it was a pretty obvious place to hide messages too. I'm sure all the other GNSS systems do it too.

They are building a BWRX-300, for around $21 billion Canadian. It's a prototype, so high costs are expected I suppose.

The Office for Nuclear Regulation has some issues with their design too: https://www.onr.org.uk/media/b...

It's mostly the usual stuff. The control rods aren't proven to be failure proof, and we have seen accidents due to them not inserting, or getting stuck, before. There isn't enough don't to evaluate loss of coolant faults, another known failure mode. While they don't rely on pumps to circulate the coolant (it's by convection), they still need it to circulate to avoid meltdown. It must circulate through cooling systems like pools or towers.

Good luck to them, but it seems very unlikely that it will be economically viable in the end.
