In telecommunications construction we are taught to make ample use of the "hammer test" when working on and around poles. The difference in sound between a good pole, a marginal pole and a completely rotten pole is quite significant.

klank commented on Amazon and the “Profitless Business Model” Fallacy   eugenewei.com/blog/2013/1... · Posted by u/serviette

They bury the important point halfway through the article: Amazon is a free-cash-flow machine and it has almost always been so. The distinction is subtle [1], but consistent (and ideally ever-growing) free-cash-flow is what really matters in valuing a highly capitalized company, even if the firm has always re-invested it each quarter to date. The important point to investors is that the firm's re-investment is a decision -- the company is not brittle to economic downturn and any quarter could decide to payout investors through share buyback etc.

Copious free-cash-flow every quarter is why software companies generally have higher valuations than traditional industries and why it was novel that Amazon, which is not obviously a software company, behaves as one financially.

Your etc. is layoffs. In this example, the "free-cash-flow" is people's salaries. I'm not personally comfortable with it being considered such a liquid asset.

Observation has proven enough to understand the meaning of animal calls. People proved they correctly identified, for example, an distressed animal call for assistance, by playing it to their peers in the wild. They go look for the distressed animal. Other calls don't provoke the same reaction.

Analogies are always possible. I believe in the philosophical context though, understanding the meaning of something is not possible through analogy alone.

Reminds me of the quote:

“But people have an unfortunate habit of assuming they understand the reality just because they understood the analogy. You dumb down brain surgery enough for a preschooler to think he understands it, the little tyke’s liable to grab a microwave scalpel and start cutting when no one’s looking.”

― Peter Watts, Echopraxia

  > But Lion is not just animal, it is not just mammal, it is something more.
Are you saying "lion" is a stand-in for "an arbitrary creature"? If so, yes, that is how I understand Wittgenstein and it doesn't change my comment.

klank · 5 months ago
No. I'm saying the areas you point out that you feel you could communicate, are ones in which you share a lived experience with the lion. You are both animals, you are both mammals. You get cold, hungry, thirsty, etc.

But lions, and us, are not just animals + mammals. Being a lion or a human means more. Ultimately, there is a uniquely human or lion element. Wittgenstein is saying we cannot communicate this.

I don't know about a Lion, but I think Wittgenstein could have benefited from having a pet.

I train my cat and while I can't always understand her I think one of the most impressive features of the human mind is to be able to have such great understanding of others. We have theory of mind, joint attention, triadic awareness, and much more. My cat can understand me a bit but it's definitely asymmetric.

It's definitely not easy to understand other animals. As Wittgenstein suggests, their minds are alien to us. But we seem to be able to adapt. I'm much better at understanding my cat than my girlfriend (all the local street cats love me, and I teach many of them tricks) but I'm also nothing compared to experts I've seen.

Honestly, I think everyone studying AI could benefit by spending some more time studying animal cognition. While not like computer minds these are testable "alien minds" and can help us better understand the general nature of intelligence

klank · 5 months ago
I think the response is generally you are communicating with your cat as an animal, as a mammal. Yes, communication is possible because we too are mammals, animals, etc.

But Lion is not just animal, it is not just mammal, it is something more. Something which I have no idea how we would communicate with.

Hmm, I'm finding the premise a bit confusing, "understand what it truly meant to be a lion". I think that's quite different than having meaningful communication. One could make the same argument for "truly understanding" what it means to be someone else.

My thinking is that if something is capable of human-style speech, then we'd be able to communicate with them. We'd be able to talk about our shared experiences of the planet, and, if we're capable of human-style speech, likely also talk about more abstract concepts of what it means to be a human or lion. And potentially create new words for concepts that don't exist in each language.

I think the fact that human speech is capable of abstract concepts, not just concrete concepts, means that shared experience isn't necessary to have meaningful communication? It's a bit handwavy, depends a bit on how we're defining "understand" and "communicate".

I don't follow that line of reasoning. To me, in that example, you're still communicating with a human, who regardless of culture, or geographic location, still shares an immense amount of shared life experiences with you.

Or, they're not. For example, an intentionally extreme example, I bet we'd have a super hard time talking about homotopy type theory with a member of the amazon rain forest. Similarly, I'd bet they had their own abstract concepts that they would not be able to easily explain to us.

If we had a sufficiently large corpus of lion-speech we could build an LLM (Lion Language Model) that would “understand” as well as any model could.

Which isn’t saying much, it still couldn’t explain Lion Language to us, it could just generate statistically plausible examples or recognize examples.

To translate Lion speech you’d need to train a transformer on a parallel corpus of Lion to English, the existence of which would require that you already understand Lion.

klank · 5 months ago
And even, assuming the existence of a Lion to English corpus, it would only give us Human word approximations. We experience how lossy that type of translation is already between Human->Human languages. Or sometimes between dialects within the same language.

Who knows, we don't really have good insight into how this information loss, or disparity grows. Is it linear? exponential? Presumably there is a threshold beyond which we simply have no ability to translate while retaining a meaningful amount of original meaning.

Would we know it when we tried to go over that threshold?

Sorry, I know I'm rambling. But it has always been regularly on my mind and it's easy for me to get on a roll. All this LLM stuff only kicked it all into overdrive.

Hmm I'm not convinced we don't have a lot of shared experience. We live on the same planet. We both hunger, eat, and drink. We see the sun, the grass, the sky. We both have muscles that stretch and compress. We both sleep and yawn.

I mean who knows, maybe their perception of these shared experiences would be different enough to make communication difficult, but still, I think it's undeniably shared experience.

klank · 5 months ago
That's fair. To me, the point of Wittgenstein's lion thought experiment though was not necessarily to say that _any_ communication would be impossible. But to understand what it truly meant to be a lion, not just what it meant to be an animal. But we have no shared lion experiences nor does a lion have human experiences. So would we be able to have a human to lion communication even if we could both speak human speech?

I think that's the core question being asked and that's the one I have a hard time seeing how it'd work.

That was a philosophical position on the difficulty of understanding alien concepts and language, not a hard technological limit.
klank · 5 months ago
I'm missing why that distinction matters given the thread of conversation.

Would you care to expound?

There is nothing really special about speech as a form of communication. All animals communicate with each other and with other animals. Informational density and, uhhhhh, cyclomatic complexity might be different between speech and a dance or a grunt or whatever.
klank · 5 months ago
I was referencing Wittgenstein's "If a lion could speak, we would not understand it." Wittgenstein believed (and I am strongly inclined to agree with him) that our ability to convey meaning through communication was intrinsically tied to (or, rather, sprang forth from) our physical, lived experiences.

Thus, to your point, assuming communication, because "there's nothing really special about speech", does that mean we would be able to understand a lion, if the lion could speak? Wittgenstein would say probably not. At least not initially and not until we had built shared lived experiences.
