Augmented by me
Before rebutting, I will restate my case. Firstly, getting another person to write your debate for you is wrong. Secondly, AI agents like ChatGPT count as a person for this purpose. Con needs to refute at least one of these claims. His Challenges might seem like they have done so. I will show why they fail to refute my case and sometimes fail to address it.
Rebuttal to Challenge 1: "Another Person" equivalence makes perfect sense in this context
Con claims that AI agents are a lower type of mind than ours, as they, "lack consciousness, intentionality, and genuine understanding", are, "sophisticated pattern-matching systems, not thinking beings", and their output, "synthesizes patterns from training data without understanding or belief". First off, I won't name names, but I can think of quite a few humans who seem to fit that description. More importantly, questions like what is going on in the AI's "mind" or whether or not the AI is self-aware are irrelevant to the key point, which is that AI-generated arguments can look human-generated. The seeming coherency of Con's argument is his own worst enemy here. By posting an argument better than what a lot of humans could come up with, he has proven my point that getting help from Perplexity Pro is like getting help from a person.
Somewhat tangentially, Con's calculator analogy reveals a destitute view of mathematicians. Research-level mathematics is the investigation of logical structures. Buying a soldering iron does not make you a welder.
Con says, "When a human presents an AI-generated argument, they're not presenting "someone else's" argument but rather the output of a sophisticated tool, much like using advanced statistical software or translation programs." Not necessarily. What if the human lied by saying they wrote it?
Rebuttal to Challenge 2: No, my plagiarism analogy does not break down, but your grasp of AI ethics does
Con claims that using AI-generated text cannot be plagiarism because AI cannot be wronged in this way like humans can be. I am not well versed in AI law, but I will not contest that the legal frameworks around plagiarism do not apply to machine-generated content. Whether or not the ethical frameworks apply is a different question. What if it turns out that AI agents are self-aware? Wouldn't they then be ethically, if not legally, entitled to not have their output plagiarized? When I said that presenting someone else's arguments as your own is plagiarism, I meant that in the ethical sense, not necessarily the legal sense.
Many societies throughout history have practiced slavery. If a slave, a human with no legal rights, wrote my argument for me, I would still be plagiarizing from them.
Citing the precedent of collaborative tools misses my point entirely. Nobody has ever written an entire debate by asking Clippy for help.
Rebuttal to Challenge 3: Nuances schmuances
Con claims that there is a significant difference between using AI to generate an entire argument and using AI for relatively minor help. No there isn't. Everything Con said here can be applied to humans as well as AI. If you asked another human to look over your debate round before you submit it and point out spelling errors, you would still be requesting assistance against the spirit of writing your debate yourself. Just because crime A is worse than crime B does not mean crime B is okay.
Rebuttal to Challenge 4: I was talking about ethical concerns, not practical ones
This challenge is a non-contention to my thesis. AI agents probably would give many debaters, i.e., the less competent ones, an advantage, but whether or not they do is irrelevant to whether or not using AI-generated content is equivalent to plagiarism. Unskilled human debaters also lack, "nuance, context-sensitivity, and genuine insight that skilled human debaters provide", yet, if Neil deGrasse Tyson copied a paragraph from a C- freshman essay, he would still have plagiarized it.
Rebuttal to Challenge 5: Not problematic! Just misunderstood!
Con misunderstands the point I was making with each of the analogies he mentioned. My motorcycle analogy was to point out that making something more superficially interesting or fun does not make it better. My boxing-gun safety analogy was to point out that AI agents can generate false or otherwise objectionable content. I never said that using AI gives as large an advantage to a debater as a Harley to a bicyclist or a gun to a boxer.
Rebuttal to Challenge 6: Same problems we had anyway
Does my proposal lack clear boundaries? Only insofar as the boundaries were unclear anyway. "Is paraphrasing AI content acceptable?" Yes when paraphrasing human content is acceptable and no when it is unacceptable. I don't need to go into details about when paraphrasing another human's words is or is not acceptable because my point stands that human and AI content are equivalent for this purpose.
"How would debate sites actually detect AI use?" How would debate sites detect if you paid someone else to write your debate for you? They might not, yet that does not mean outsourcing your debates should not be banned. Even if a ban were practically unenforceable, which Con suggests but does not establish beyond a reasonable doubt, this would not make a de jure ban wrong.
Rebuttal to Challenge 7: The "Context" approach ignores that plagiarism is wrong
Con says, "Academic exercises, casual discussions, and competitive tournaments might reasonably have different standards for tool usage." One thing that academic exercises and competitive tournaments have in common is that plagiarism is wrong. I accept that academic exercises could generally allow for use of AI-generated text, at least if the text is disclosed as AI-generated, but that is no different than having a co-author on a research paper. As for competitive tournaments, if the tournament is mano-a-mano (or meno-a-meno, if each side has more than one human), then using AI-generated text is plagiarism. I could see a tournament that specifically allows AI assistance, but this would need to be in a separate category from normal debates, and, as I said in the previous round, I consider this cordoning off to be a form of ban.
Rebuttal to Con's "Fundamental Philosophical Objection"
Con claims my argument rests on the "naturalistic fallacy" that debate "must remain "purely human" to be valuable". My argument actually rests on the claim that debate must remain purely the work of one human or specified group of humans to not be cheating.
Con says, "The question isn't whether AI assistance is "natural" but whether it serves the underlying purposes of debate: testing ideas, improving arguments, and advancing understanding." Again, Con missed my point entirely. The question isn't whether AI assistance is better than human assistance or readily detectable or easily accessible to anyone with an Internet connection. The question is whether or not AI assistance is, in the context of debates on a debate site, morally equivalent to human assistance. I believe I have shown that it is and refuted Con's attempts to show otherwise. Con repeats this mistake in the next paragraph: "Your framework treats AI assistance as categorically different from other cognitive enhancements (education, training, research tools) without adequately justifying this special status." Con has it backwards. Con treats AI assistance as categorically different from human assistance without adequately justifying this special status.
Con closes with, "This suggests your position may be driven more by intuitive discomfort with AI than by principled reasoning about debate ethics." Ah, yes. AId hominem.
