I keep seeing posts about this kind of thing getting people's hopes up, so let's address this myth.
What's an "AI detector"?
We're talking about these tools that advertise the ability to accurately detect things like deep-fake videos or text generated by LLMs (like ChatGPT), etc. We are NOT talking about voluntary watermarking that companies like OpenAI might choose to add in the future.
What does "effective" mean?
I mean something with high levels of accuracy, both highly sensitive (low false negatives) and highly specific (low false positives). High would probably be at least 95%, though this is ultimately subjective.
Why should the accuracy bar be so high? Isn't anything better than a coin flip good enough?
If you're going to definitively label something as "fake" or "real", you better be damn sure about it, because the consequences for being wrong with that label are even worse than having no label at all. You're either telling people that they should trust a fake that they might have been skeptical about otherwise, or you're slandering something real. In both cases you're spreading misinformation which is worse than if you had just said "I'm not sure".
Why can't a good AI detector be built?
To understand this part you need to understand a little bit about how these neural networks are created in the first place. Generative Adversarial Networks (GANs) are a strategy often employed to train models that generate content. These work by having two different neural networks, one that generates content similar to existing content, and one that detects the difference between generated content and the existing content. These networks learn in tandem, each time one network gets better the other one also gets better.
That this means is that building a content generator and a fake content detector are effectively two different sides of the same coin. Improvements to one can always be translated directly and in an automated way into improvements into the other one. This means that the generator will always improve until the detector is fooled about 50% of the time.
Note that not all of these models are always trained in exactly this way, but the point is that anything CAN be trained this way, so even if a GAN wasn't originally used, any kind of improved detection can always be directly translated into improved generation to beat that detection. This isn't just any ordinary "arms race", because the turn around time here is so fast there won't be any chance of being ahead of the curve... the generators will always win.
Why do these "AI detectors" keep getting advertised if they don't work?
- People are afraid of being saturated by fake content, and the media is taking advantage of that fear to sell snake oil
- Every generator network comes with its own free detector network that doesn't really work all that well (~50% accuracy) because it was used to create the generator originally, so these detectors are ubiquitous among AI labs. That means the people that own the detectors are the SAME PEOPLE that created the problem in the first place, and they want to make sure you come back to them for the solution as well.
Okay, interesting. Of course it would be nice if languages were easy to understand and easy to learn. German seems to be on the hard end of this spectrum, but no language is free from unecessary complications like these. They all grew historically and organically, and were not constructed with accessibility in mind.
It is nearly impossible to get an objective view on languages, since each of us is inherently biased, and most of us don't speak another language so well that we could truly judge it. It's easy to spot silly things in other languages while we may be unaware of how difficult our mother language is to learn for foreigners.
The interpretation of the given examples feels wrong for me. While the technical part is correct, I think the conclusion is incorrect. For example, "Unabhaengigkeitserklärung" emphasizes the independence, while "Erklärung von Unabhängigkeit" emphasizes the demonstration. The two are not equivalent. Twain seemed to be ignorant about that and simply assumed a foreign language would follow the same rules as his own.
While I can understand Twains frustration in learning another language, his critique is based on a lack of understanding.
For some compound words, there is no straightforward equivalent. "Apfelbaum" (apple tree) could be "Baum, an dem Äpfel wachsen" (tree on which apples grow). But that leaves the question wether it's still an Apfelbaum when it does not grow apples in this moment, like in winter. "Baum des Apfels" (tree of the apple) can refer to a miniature tree on an apple. "Baum der Äpfel" (tree of the apples) might be okay.
Further, what he believes to be superior can sometimes be inferior. Consider cases like "The presentation on renewable energy technology investors." In this sentence, it's not clear whether "renewable energy technology" is a single entity modifying "investors," or if "renewable energy" and "technology investors" are separate entities, both modifying "presentation." The sentence could refer to a presentation for investors interested in renewable energy technology or to a presentation about investors who focus on renewable energy projects. Compound words prevent ambiguities like these.
Hyphens can help in these cases. They can also be used in German to make it easy to identify compound components, like it's required in https://en.wikipedia.org/wiki/Leichte_Sprache.
That's another interesting point to discuss. Which is easier for foreigners? Sure, a single, short word in itself is easy to learn. But it is a new word, which has to be learned. In this case, you have to learn which part of "memory" or "memorize" can be used, and which part must be replaced.
I also don't think "memorable" has the same meaning as "never-to-be-forgotten". Isn't "memorable" more fitting for positive things, while n-t-b-f is well suited for negative things? Was the Holocaust 'memorable'?
Honestly, I posted it more because I thought it was funny than anything. I didn't expect such a deconstruction, but it's interesting!
