That is truly terrifying. I hope that those clicking “likes” understand what this is and like it as an amusing thing to do rather than that this is a good “review”.

It raises all sorts of ethical questions many of which may already be familiar from comments about online reviews and/or those that come without laboratory measurements.

The obvious next step would be to pose the same instruction to ChatGPT but now change “positive” to “negative”.

Yes, but I don’t understand what you are trying to show. That this is rubbish ( after all ChatGPT has never “heard” Beethoven nor any other music let alone ever been in contact with a Rossini )? or are you saying “look, here is the output of a machine, can you tell it from a review written by a human?”. Or what?

Further this thread alone has already produced an ethical problem. Search engines are unable to tell that these ChatGPT outputs are not real reviews but just API “essays”. Google is already finding your postings as actual reviews and listing them in searches as such. This is dangerous stuff and at the very least misleading to uninformed searchers.

@Phil , my opinion is that these postings severely harm the credence of this forum and should be removed. Sorry @keiserrg.

Hi Pete,
I didn’t really have a specific agenda with the post, more a demonstration of this incredible (and yes, I agree, potentially dangerous) technology.

I can imagine that editors and journalists around the world will be very tempted to use ChatGPT for all types of tasks, including audio equipment reviews, that influence our purchase decisions.

Since Deep Mind (in the UK) has announced its algorithms can now solve mathematical functions, in the future, dCS engineers may be able to ask an AI: “How can I improve this signal processing algorithm?”

Re: your callout to @Phil (?), I disagree that a post with the title of “ChatGPT review of Rossini APEX DAC,” “severely harm[s]” the credibility of this forum.

If that were to be the case, ostensibly you have identified other posts that you also feel inflict harm? What other content do you believe we should take down Pete? Or, do you believe we should not discuss AI in general?

No I do not think that discussion is harmful. What I do think of as harmful is postings that are untrue ,claiming that an activity has taken place when it hasn’t. I also think that recommendations to undertake dangerous activities or those that have high chances of causing damage should not appear. Of course these AI essays ( they are not reviews) are at least not guilty of the latter.

I appreciate that this is a new toy to you that you are impressed. But by posting these as reviews you immediately damage the credence of future reviews, real or otherwise.

Absolutely hilarious.


So, you believe that (a) posting about a new technology and clearly labeling it as such will “damage” the entire forum; and (b) such “damage” will be a direct result of my actions.

I wish I had realized earlier in life that I was so influential! (!) : )

The point has been explained. Third parties e.g search engines are already posting this piece of AI as a bona fide review. That is why the credence of this forum has been damaged.

Would you be happier with the new thread title, @PAR? I wonder how much of your concern is down to it not being clear enough that the article was written by something that couldn’t possibly have heard a Rossini Apex. Maybe our next step in audio purchase decision-making is outsourcing not only the ears’ job, but also the explaining of what the ears heard :slight_smile:

(I had no idea I could change other people’s thread titles. My new-found power is bound to get me into trouble. Someone take away my keyboard, quickly! With apologies to @keiserrg!)


What are the dangers of a ChatGPT-generated Review of Rossini APEX DAC?


While ChatGPT can generate content, including reviews, it’s important to be aware of certain potential dangers and limitations associated with relying on its output, especially for specialized and technical topics like the Rossini APEX DAC. Here are some considerations:

  1. Accuracy of Information: ChatGPT may not have the most up-to-date information, as its training only includes data up until January 2022. Therefore, it might lack awareness of the latest developments, updates, or releases related to the Rossini APEX DAC.

  2. Lack of Personal Experience: The model doesn’t have personal experiences or firsthand knowledge. It generates content based on patterns learned during training. As a result, it may not provide insights from practical usage or real-world testing of the Rossini APEX DAC.

  3. Potential for Inaccuracies: ChatGPT may generate information that is factually incorrect or misleading. Users should independently verify details from reliable sources, especially for technical products like audio equipment.

  4. Limited Understanding of Context: The model may not fully understand the specific nuances, technical details, or intricacies of the Rossini APEX DAC. It might provide generic information that may not be entirely relevant or accurate in a technical review.

  5. Bias and Subjectivity: The generated content could reflect the biases present in the training data. It’s important to consider the output critically and supplement it with diverse perspectives and information from authoritative sources.

  6. Absence of User Preferences: The model cannot consider individual preferences or priorities. A review generated by ChatGPT might not align with your personal preferences or priorities when it comes to audio equipment.

  7. Ethical Considerations: Since ChatGPT is a machine learning model, it’s crucial to use its output ethically. Avoid spreading misinformation, and acknowledge the limitations of AI-generated content.

To mitigate these risks, it’s recommended to use ChatGPT’s output as a starting point for research and verification. Cross-reference the information with authoritative sources, expert reviews, and user experiences to form a comprehensive and accurate understanding of the Rossini APEX DAC or any other product.


Thanks to you and @all2ofme .The list of considerations when posting reviews is excellent. It echoes the problems that academics are being faced with in regard to AI especially those teaching at college level . Why would students sweat away writing essays when an AI source simply has to be asked to write 10,000 words on , say, Class Distinctions in 19th Century English Novels? Full of comparable pitfalls.Remedies are being developed but these inevitably ban such use to ensure that essay’s are the student’s own work. I think the moderators have to impose a similar rule here. I think we might all agree that ChatGPT’s output is highly convincing and difficult tell apart from a genuine review to those unaware of the source or who may, for example, assume that ChatGP is a magazine or a group with a common interest ( like a Whats’App group) . After all five days ago I had never heard of it. BTW, Google has retained its link under the original title despite the change.

Changing the topic title ( I guess I have similar authority) helps but I don’t think solves the problem with search engines or readers lacking sufficient knowledge. Irrespective of this the text still claims that it is a review. So it will still have a further life as if it was genuine even though it is imaginary. It may coincide with our likely feelings about Rossini but only because it reflects the instructions given to it and serendipity.

Coincidentally I have spent a few hours this week watching the annual Royal Institution Christmas Lectures on TV. This year all about AI. Pitched at children it was at my intellectual level :wink:.

Just adding my 2cents on this;

Whether we like it or not, this genie is out of the bottle and there’s no stuffing it back in (AI/ChatGPT I mean, not keiserrg’s post :laughing:). Thousands of people are already using it to augment their daily work. ChatGPT alone crossed $1.3Bil in revenue since Oct’23. Google Gemini/DeepMind won’t be far (if you want to be truly scared, watch Gemini’s multimodal demonstration).

In the context of Audio equipment reviews though, I see this as a good thing. There are far too many reviewers whose content are hardly different from what ChatGPT can apparently generate in 10 seconds. IMHO, these “reviewers” either need to find ways to differentiate (like including objective measurements :grin:), or find another job. So, I definitely don’t see any harm in keiserrg’s post/this thread.

Likewise, buyers who rely on or are convinced to spend money purely on the basis of such reviews need to learn to be far more decerning.


I certainly have sympathy with this view but leaving it just as “Caveat Emptor” is not sufficient IMO.

I’m still running amok with my thread-title-editing powers and have doo-hickified the word “review”.

I’m sure the change will take a while to propagate across teh interwebs, but maybe the extra clarity will help someone impressionable steer clear of these Rossini Apexes. (More for us! :stuck_out_tongue:)

Fun! Thanks for doing that!

Please, let us not start editing each others posts without prior consent. :face_with_raised_eyebrow:


Thank you for your post @Ermos.

I’m so glad that destroying the credibility of this forum was not one of the concerns that ChatGPT identified.

@all2ofme is already running amok! I hope he doesn’t change my system without my consent. I don’t want to wake up and find out my Rossini has been replaced with a Chord Mojo (!)

; )


Hee hee — your Boulder is way too heavy for that :slight_smile:

I promise not to misbehave. The thought that I might piss people off was a big one, but I balanced it with having met both @PAR and @keiserrg in real life and hoping (:crossed_fingers:) that my meddling would be taken as intended — a speedy way to explore a topic that had already led to some het-up posts. (I was also fascinated to find a button where once there was none. Who among us wouldn’t press an exciting new button on the front of their DAC?!)

I’ll steer clear in future, @Ermos, and appreciate your candour, as always :blush:


ChatGPT (and others) have a tendency to make pronouncements based on musings rather than hard fact. The Nigel Farage of the digital world.

Very dangerous in the wrong hands and can even influence the outcome of elections.


And even more dangerous, I am presently going through @all2ofme’s prior posts on this forum and debating if there are any titles I want to change.
