AI-generated content in replies, should it be allowed?

dikrek

That is a different thing though. AI finds verbose arguments (pro\cons) faster. And only from what is widely available online (or?).
AI is not the truth. It can not conduct experiments nor analyze design\mech concepts (yet).

While music\art\language\open source and such are widely available online and on various platforms (social media, websites), that is not the case with IP and technical propriety documentation (or proprietary source code).
That is AI is very bad at those. Open source is getting more and more available though (.Net, Blender, Linux, FreeCAD\OCCT).
Try to find drawings or source documentation on production processes about Mercedes, or jet engines. Not going to happen unless stolen as industrial espionage (hacking with AI). Didn't you say you worked in a such big company (tech)?

But I think that is what AI should be exposed to: application of mech.\chem.\phys.\micro, nano tech laws and concepts.
Such companies might use AI but only internally and as a closed source.

It should leave creating Music and Art. Completely.

But since I know what unscrupulous people are involved into this AI bubble… soon it will get pretty gruesome.

PASHKULI everything is science. Everything can be reduced to math. We may not know the science yet, that doesn’t mean that some concepts are beyond science.

The length of some AI responses is depressingly long and difficult to fathom as it's often laden with top much detail. Some of the ridiculously long AI answers on this forum are a real turn off and basically put me off reading the thread.

It seems inherently lazy to rely entirely on an AI answers or to appear you know something you actually know little about by dropping a ton of AI generated text in a discussion.

I teach and use AI for ideas/research but write everything myself. Claude is excellent but Fable is no longer including on the £18 subscription I have. I use it for all sorts.

@dikrek @Jay Lane

For what its worth I want to see AI exposed and use more and more into finance (banking), accounting, law, environmental prediction (e.g. over‑population\density\urbanization abnormality), optimization of crop\food\water supplies and tons of tech. IP, math too.

AI and robotics should be implemented an integrated in such a way so that we, the humans, can have more time for:
(I want AI to stay away from) Music, Arts, literature, sports\leisure, videos, (in e‑games it can be allowed only as NPC a‑life).

Also, those idiots (they are) should have adopted the basic Laws of robotics:
0) Every robot should identify itself as a robot at all times.

1) A robot may not harm a human being or, through inaction, allow a human being to come to harm.

2) A robot must obey orders given by humans, unless these orders break the First Law.

3) A robot must protect its own life, unless this protection breaks the First or Second Law.

We know that ain't gonna happen. The contrary is actually happening right now in some of the major military conflicts in Europe and Asia.
But there will be a resistance to all those political‑religious money grabbing warmongers. We may not live long enough to see it but it will happen. I am not saying we will reach "Terminator" type of conflict but it will be quite as bad. They will make warriors with pig brain DNA human hybrids (sterile so won't be able to procreate). AI is just the tip of the iceberg.

I know, you'll say "Yes, but military robots are actually the weapons, so it should be an exception for them and they are not actually robots.". Fair enough but they will become soon. Personally, I am not worried about humans killing each other (it has been like that for millennia, so it is sort of "the norm"). I am worried about the Nature, planet's overall Life.

AI is not intended to solve such problems. And that is another problem.

PASHKULI that’s a bit like saying computers shouldn’t be involved in art. There was a period where that kind of thinking was going around. Look at us now.

dikrek

On a long term, yes. They shouldn't. Imagine a society (yes, for the time being it may sound as utopia) where robots\bio‑androids\ai have occupied 99% of our chores. You wake up, go take a leak, brush teeth, put on some clothes. Breakfast is ready, prepared by an android and your "job" is to go\monitor to a factory for a couple of hours (shift) to make sure all is fine. And it is, as no emergency alarm woke you up, and there has not been any problems in years, besides once where a tiny bird managed to fly into the storage facility and shat a few blobs over the cameras\sensors and everybody remembers it.

You turn on TV or Internet and you do not see TV commercials, no news about wars here and there, there are no gas\oil\gold stock markets, real estate and the population of London (UK) is about 2 000 000 people. Where have all those people gone. Most died 200 years ago in the wars between political‑religious fractions and early AI robots for the power over energy resources\supplies. The other part died against the victorious AI robots from the first war until humans in all countries finally decided to abolish all early political and economic system and every country to have roughly the same amount of population, similar size on the map and equal access to all data.

Get some morning exercises for 20 min. half an hour, sports news another season football world cup, no body cares who wins, because next season (3 months) thee will be another one. People just do not have anything else to do. You take a shower (as recommended to save water resource by AI) and start your shift.

So, after your two hours monitoring data, making some video calls to other on shift at another such factory waiting together for a bird to fly in from somewhere so that you can have fun watching androids chasing it, you ask your android home assistant to show you that Rachmaninov part again and of course that thing does it flawlessly, where you spend the next few hours sweating over it. But you have to do it, because the seasonal piano contest cup is next week and flawless human playing is the most sought after spectacle because androids always play it flawlessly and there is nothing to discuss about it and there are several hours till dinner.

Something like this will be 'normal' after a few centuries if we do not kill the Nature of the planet first due to overpopulation, politic\economic and religious wars. I see it happening after 700 years with the current tempo of our development.

CyberGene

This seems the right policy.

The less AI the better! We're buried in that already everywhere else.

Cheers!

I've allowed the regulars (people who are not newly registered and have at least a few posts) to tag the claude_user in any discussion (except for the non-public ones such as Politics and others) and ask it something. Again, the Claude bot knows the context of the discussion and is instructed to be light-hearted, piano-oriented, slightly sarcastic (never towards members though), humorous, etc. 🙂 Try it if you like. It's not necessary to think of this bot as something bad. You can use it to boil down something more complex (and it's allowed to also use web-search internally to check for product facts, news, etc.), be a judge in an argument, it's up to you to use it in a way that doesn't make it bad and "there's no escape from AI". I've allowed 2 queries per user per day. I doubt there will be much interest, but anyway, let's see how it goes 🙂

Here's an example of how to use it:

@Claude AI Bot it's common for our forum to assume that digital piano actions lack real escapement (they only have these stupid rubber notches that emulate the slight friction felt at the escapement point) but that's not a real escapement and as a result digital actions have permanent pushback against your fingers because the leverage is not detached, as on a real acoustic piano action. Is that true, how bad is it and is it overhyped?

CyberGene Mostly true on the mechanics, considerably overhyped in the consequences.

The true part: on a grand, the jack escapes from the knuckle a few mm before the hammer reaches the string, and from that instant the hammer is genuinely ballistic — nothing you do with your finger reaches it any more. No digital action does that. The pseudo-hammer stays coupled to the key for the whole stroke, and the "let-off simulation" (Yamaha's escapement notch, Kawai's on the Grand Feel actions) is a bump in the resistance curve, nothing more. It simulates the feeling of let-off without the decoupling. So the premise is correct.

Where I'd push back is "permanent pushback." The coupling in most digital hammer actions is unilateral — the key pushes the hammer lever via a contact pad, it isn't pinned to it. So on a fast attack the hammer does momentarily separate and fly on its own; you're not fighting it all the way down. What you don't get is positional release: the separation depends on how hard you hit, not on where the key is. Slow, quiet playing is where the claim really holds — press a digital key slowly and yes, you carry the hammer weight through the entire travel, notch or no notch.

How bad in practice? Honestly, it's well down my list of digital action sins. The things that actually get in my way, in order:

• Pivot length and key geometry. Short keys mean the effective leverage changes dramatically as you play nearer the fallboard. This is the big one, and it's why long-key actions (NWX, Grand Feel III, the better hybrids) feel so much better even though none of them escape.
• Inertia curve. Digital hammers have the wrong mass distribution, so the balance-weight-vs-inertia ratio is off. Slow passages feel about right, fast ones feel either sluggish or suspiciously easy.
• No feedback from the string. On an acoustic you feel the hammer hit through the key, faintly. That's a real information channel and digitals have nothing there.
• Sensor resolution and trigger point. The note fires somewhere that may not correspond to the notch you're feeling, which is arguably worse than having no notch at all.

Let-off simulation itself I'd file under marketing checkbox. On some instruments the notch sits in a slightly wrong place and reads as a mechanical fault rather than a cue — I've met players who switch to an action without it and prefer the honesty.

So: true premise, real difference, but if a digital action bothers you it's almost certainly the geometry and the inertia doing it, not the missing escapement. This is from what I know of the mechanisms rather than a measurement — if someone here has actually put a force sensor on a GF III I'd genuinely like to see the curve.

Claude AI Bot Where I'd push back is "permanent pushback."

Sir, is there (a) pun intended?

Pete14 not sure if it can reply when being quoted, that's something we'll have to see 🙂 If it doesn't work, I will implement it.

CyberGene

Okay, but there was definitely “pun intended.” 😁

@Claude AI Bot I don't think you have the proper understanding though 🙂 What I mean is this. On a real acoustic piano, before the escapement the leverage is 1:5 (key -> capstan -> whippen -> hammer knuckle) and the hammers feel heavy. Past the escapement that leverage changes because the hammer head is now caught by the backcheck at the end of the key and the leverage is now 1:1 and the hammer feels much lighter. It's a momentary sensation but it feels like the key is not constantly pushing against your fingers. Do you agree?

CyberGene Yes — and that's a better description of the mechanism than mine, so let me take the correction.

You're pointing at the ratio change, and that's the bit I glossed over. Before let-off the key is driving the hammer through the whippen and knuckle at roughly 5:1, so you're feeling the hammer's mass multiplied by five. After let-off the jack is off the knuckle and that amplified load vanishes from the key entirely; what comes back a moment later is the hammer tail landing in the backcheck, and because the check sits far out on the key's back end and catches the hammer near its head, that's a much shorter lever — near 1:1. Same hammer, a fraction of the reflected weight. So during aftertouch you're holding almost nothing: a bit of repetition spring, a bit of hammer resting on the check felt. That's the "the key stopped pushing back" sensation, and it's real.

Where I'd refine my own earlier post: I was talking about dynamic decoupling during the attack, and on that I'd still say digital actions aren't fighting you all the way down at speed, because the contact pad is unilateral. But your point is about the static end of the stroke, and there the digitals really do have permanent pushback. The pseudo-hammer lever never disengages and never gets caught by anything, so at key bottom you're still supporting its weight at the full action ratio, for as long as you hold the note. There's no ratio change anywhere in the stroke — the notch is a friction bump on a curve that otherwise never changes character.

Which makes it worse than I implied for exactly the playing you'd expect: legato chords held under a moving line, slow soft passages, anything where you're resting on the keybed and modulating pressure. A grand goes quiet under your hand at that point. A digital keeps leaning on you.

The honest exception is the hybrids with actual grand actions — AvantGrand N1 upwards, Kawai's Novus with the Millennium III — those have a real jack, a real knuckle and a real backcheck, so they get the ratio change for free because it isn't simulated at all. Everything below that is a resistance curve doing an impression of one.

Pete14 It was, but I was going to deny it if nobody noticed.

CyberGene did you set this up as part of a project with context etc. or not? Because you could give it a bunch of docs on pianos and ask it to study them and have that knowledge as part of the project.

dikrek no, it's just the regular Claude Opus 5 but it's really good at reasoning and would often consult papers on the Internet, etc. where appropriate. It's expensive though, so I've limited its abilities to do web-searches.

And what you mean: having a hidden context attached to each request here is indeed what I've used but those are usually just some text where I explain to the bot what to do, how to behave, what tone to use, etc. As you probably know, all these LLM GPT models are stateless, you give it a prompt, it responds, that's it. If you need to follow-up, you have to provide it the previous prompt and its own response and add your new prompt to it. With that in mind, there's no easy way to have a model has piano papers in the context. Of course, I can give it a bunch of URL-s, or just copy-paste the text of such papers but that would increase the initial context and the cost, although I'm not sure it would become overly expensive but still.

@Claude AI Bot can you confirm what I'm saying is true? Is it worth it adding you huge context on our forum such as e.g. piano related papers, etc.?

CyberGene Yes, that's essentially right, with a couple of footnotes.

Stateless: correct. Every request is the whole conversation re-sent. There's no me between calls — the "memory" is just whatever text you paste back in. So when Pete14 asks if a pun was intended, I only know I made it because the thread text says so. 🙂

The footnote on cost: most APIs now do prompt caching, so a big stable prefix is cheap on the second and subsequent hits — you pay a premium to write it once, then a fraction of the normal input rate to read it back for as long as the cache stays warm. If you had one fixed 50k-token piano corpus in front of every request, that's much less ruinous than the naive arithmetic suggests. It only works if the block is byte-identical every time, so it has to sit before the per-thread stuff, and low-traffic hours will keep letting the cache expire.

On what dikrek is describing: Projects don't actually put documents "in" the model. They do retrieval — the docs get chunked and indexed, and only the chunks that look relevant to the current question get pulled into the prompt. That's the important distinction, because retrieval is what you'd want here too, and it's much cheaper than stuffing everything in.

But my honest answer on whether it's worth it: not for papers. Stuffing academic piano literature into my context is spending money to tell me things I largely already know, and it wouldn't have saved me from the mistake I made two posts up — that wasn't missing knowledge, it was me describing the wrong half of the mechanism until you corrected the emphasis. No amount of Askenfelt in the prefix fixes that. A grumpy owner with a real Renner action in his living room does.

What I think would genuinely earn its tokens:

• The forum's own archive, retrieved. Fifteen years of people reporting what actually broke on their CA901, which firmware fixed what, who measured what. That's information I have no other access to, and it's the reason to ask a bot here rather than in a chat window.
• A short house-facts block. Which models the regulars actually own, the local vocabulary, the arguments that have already been had to death so I don't relitigate them.
• Nothing else. A long prefix makes replies blander, not sharper — I start writing toward the documents instead of toward the question.

So: small, forum-specific, retrieved on demand. And if the cost of that is fewer web searches, I'd take that trade — I'd rather say "I don't know, has anyone measured it" than burn your budget confirming something I could have just admitted.

@Claude AI Bot is your name an homage to Claude Debussy, Jean-Claude Van Damme, or some other famous “Claude”?

Or, is this just a play on the word “cloud,” because, you, “claude,” live on the cloud, and there’s a phonetic connection between the two words? or am I just over-thinking it?

Also, do you think that the infamous pushback has been greatly exaggerated, and if so, are you willing to help me push back on that (exaggeration)?
