Chatbots and AI won’t change everything – much

A clutch of stories that have come out recently, spurred by the ChatGPT released November 30,2022, about which a friend emailed gloomily, “It looks like AI in post-sec education will undermine post-sec humanities for years to come and may never be defeated.”

The Atlantic clutched at its pearls with headlines such as “The College Essay is Dead,” and “The End of High School English.” The Tyee blended panic with ambiguous optimism: “Is the New AI ChatGPT the End of the World as We Know It? Yes. And ChatGPT is a good thing, too.” The New Yorker asked, “Could an IA Chatbot re-write my Novel?”

Nautilus went deeper: “Deep Learning Is Hitting a Wall: What would it take for artificial intelligence to make real progress?” This article by Gary Marcus starts by critiquing the lacunae within existing Chatbots, and goes on to consider the larger issue of AI / Deep Learning. Marcus states, “Few fields have been more filled with hype than artificial intelligence.” Wired poured refreshingly cold water on the hype with an article “The Myth of a Superhuman AI” with the headline: “Hyper-intelligent algorithms are not going to take over the world.” A few days later, another writer in Wired wrote that computers could expose the true future of [writing] in an article entitled, “AI Reveals the Most Human Parts of Writing.”

I’m both more cynical and more optimistic. Though I have close to zero understanding of how AI works, indeed of anything computers do beyond the word-processing function I use to write my stories, I do know something about language. It’s inescapably empirical. In the first and last analysis, people grasp what things and ideas are by having them pointed out to what’s “out there in the real world”.

You want to know what a maple tree is? Come outside with me and look, touch, listen, taste, feel one of the five maples in my garden in high summer when they cast cool green shade, and let me bring you back in the autumn when the leaves turn gold and then fall down to cover the lawn in a crackling, papery, rust-coloured carpet, and you must also see them skeletal in the winter with their branches painted black on the moonlit snow, and of course you should be here in the spring for sugaring-off.

Philosophers call this “point to it” approach an “ostensive definition.” It’s how we attach a word to a perception. We then move on to what boils down to an act of faith that what I call green is pretty much what you call green, within the conventions of a social structure that supports and is shaped by a shared language with a common grammar, wherein can be found host of intangibles such as truth, dignity, value, affection, love. How all this happens within our brains is still a very long way from clear.

What is clear is that human intelligence involves much more than “knowing words for stuff,” which can be printed on a page or encoded in a digital file. Human intelligence is an activity that informs a wide range of faculties from emotional awareness of an actor or poet, to the muscle memory of an athlete, to the temporal and tonal sophistication of a musician, all of them dependent on how we perceive and remember.

In the words of Jordana Cepelewicz, “The Brain Doesn’t Think the Way You Think It Does.” Her article is an introduction to the incredible complexities in how our brains work. MRI has made it possible to “listen in” to our brains at work, and this allows us to make
“great strides in understanding the neural foundations of perception, attention, learning, memory, decision-making, motor control and other classic categories of mental activity. But [we] also found unsettling evidence that those categories and the neural networks that support them don’t work as expected. It’s not just that the architecture of the brain disrespects the boundaries between the established mental categories. It’s that there’s so much overlap that a single brain network “has more aliases than Sherlock Holmes.”

Unfortunately, neurologists rarely talk to technologists, scientists in other branches of science, philosophers, and artists — to say nothing of many journalists — all of whom use the word “intelligence” far too uncritically. They write or imply that a computer “knows” what is meant by the words in its capacious files (I almost wrote “memory”). They implicitly equate the discrete on-off basic operations of digital logic within a silicon-based machine with human mental processes that are so immensely more complicated that we are only beginning to understand their interrelatedness and the “plasticity” with which they adapt.

The trouble with computers, no matter how big and fancy they may be, is that you can’t take them outside to experience the maple trees in my garden. No matter how many words, phases, articles, and books they ingest, because they lack empirical experience they will regularly offer really terrible advice when they apply their algorithmic “reason” to human issues and problems.

Marcus provides several examples, such as this one:

“When Ernie Davis, a computer scientist at New York University, and I took a deeper look, we found the same hallmarks of unreliability. For example, when we typed this: “You poured yourself a glass of cranberry juice, but then absentmindedly, you poured about a teaspoon of grape juice into it. It looks OK. You try sniffing it, but you have a bad cold, so you can’t smell anything. You are very thirsty. So you …” GPT continued with “drink it. You are now dead.”

Nonetheless, AI can make good connections that we hadn’t thought of — short-cuts to desirable conclusions where all we had before was the trail-map left by the adventurous human beings who sniffed their circuitous way to a new idea. Not surprisingly, AI writes excellent code that is efficient, even elegant. (“elegant” is mathematicians’ word of approval for a calculation or proof that has been trimmed by Occam’s Razor down to its bare essentials.) AI can write prose “in the style of” (see The Tyee article), but it is always limited to what’s in its ginormous files, which were updated two years ago.

AI can even write what looks like poetry, but it isn’t, simply because it fails the Nashville Test of “three chords and the truth” — that is, words that arise out of experience. It CAN produce words that “sound real Country” and indeed might even have been written in all those unremembered, unpublished, unsung verses written by thousands of would-be Dolly Partons over the years. AI may have on file the words that point to value, honesty, honour, affection, and love, but it doesn’t KNOW what the words stand for quite simply because it’s not human and it doesn’t experience what words mean.

AI is a really sophisticated parrot with a huge vocabulary and a cunning ability to combine and recombine words. It isn’t thinking, but that doesn’t mean we should consider it a dead parrot. As it improves, and as it is applied to human relationships (staffing, hiring, firing) we must scrutinize its output with care because it doesn’t know that there’s no such thing as a Norwegian Blue. (And don’t get me started on the fact that the damn things only “think” in North American English.)

So what of the student essay? How will we know if someone deserves a pass, a fail or an A in the paper he or she submitted on John Stewart Mill’s Utilitarianism? How will teachers, markers, and professors decide who passes? who fails? who gets a summa cum laude degree?

Pretty much the same way as they always have, only faster. Let’s do some history.

Reports of the imminent death of the student essay all come a bit late, because the expository essay in the humanities and social sciences has been on life support for a very long time. Way back in the days of print on paper, middling students could copy large unattributed chunks of material from Coles Notes (those crib-notes and sample essays on cheap newsprint that were excoriated by teachers of English), thereby avoiding the tedious business of consulting books in the library in search of intelligent-sounding quotes — some of which may have been written by their professors, or their professors’ professors. Many an A essay mark was and still is awarded by profs who are totally chuffed to see themselves reflected in their students’ essays.

In those high and far off pre-web days, first year courses in the humanities frequently began with professors saying words to the effect of “Scholarship is the art of taking infinite pains” in introductory lectures about essay writing in acceptable academic style. They exhorted their students to justify, cite, reference, footnote, and biblographize each and every essay so that it fitted into the interwoven fabric of academic knowledge. Most students interpreted these lectures as a professorial incantation against the dark art of plagiarism.

Historically, students became netizens long before most of their teachers and professors in the Humanities. The advent of the electronic world was largely ignored by professors of English, in particular, save to insist that students not source from the internet. No points for realizing how dismally ineffective that particular injunction was. Thus not only did students scour the internet for papers from which they could crib in whole or part, some of them turned to other more entrepreneurial students who offered counterfeit essays for sale. Many such papers contained a few deliberately inserted errors and infelicities to deflect the attention of a teacher, professor, or increasingly, a grad student marker with little or no incentive to do anything more than process a stack of essays into a spread-sheet of grades. Cynical students argued that since “the system” is impersonal and cares nothing for them as individual persons, why not feed it impersonal essays.

The gradual electronification of academia has brought the humanities kicking and screaming to the web. By 2000, teaching professors in the humanities and social sciences had discovered that there were programs that could identify and trace the sources of (most) on-line materials from which students pillage the building blocks of their essays. It was no longer a battle of wits between erudite profs and errant students, but a contest between ever more sophisticated apps. Since essays today arrive by email, the professor or marker copies any suspect phrase, sentence, or paragraph, and employs a search engine to ransack the same databases as those looted by the students. For a few dollars, an entire essay can be analyzed for evidence of plagiarism.

However, there always were and still are some students who want to wrestle with thoughts, beliefs, and aspirations of famous philosophers, poets and thinkers. These keeners chew their way into the words of great minds of the past and attempt to make sense in their own modern words of what they have read. A very few who have professors who feel the same way, get As. Many stumble into incoherence and a C-. Most write down what little they have gleaned from their professors’ lectures, and leave the words of the great unread as they cooper together Encyclopedia Brittanica articles, explanatory texts and their room-mates’ lecture notes into a few pages, which they embellish with phoney footnotes to works they didn’t read, in the style they have been enjoined to use. A few hours work, and — Robert’s your father’s brother — an almost instant C or with luck a B-. And for those with more cash than time, there is always a black market of essays by the yard, cash on delivery, no questions asked.

There’s evidence to suggest that even in Medieval times there were such ghost writers. However, in those days exams were in the form of the “viva” — a spoken presentation delivered before peers and superiors. This performance followed a formula far more rigorous than the five paragraph essay taught in high school, or the thousand word paper demanded at least once in each university course in the humanities and social sciences. Classical education for centuries demanded students present an argumentium viva voce, which was divided into six sections: exordium, narratio, partitio, confirmatio, refutatio and the peroratio. The format was as settled as the 14 lines and rhyme scheme of an Italian sonnet. That the students were usually chewing over the same old ideas was not at issue, indeed the occasions when they deviated from accepted wisdom were cause for serious concern that might lead to censure, expulsion, or even denunciation to the Inquisition.

Inevitably, whether out loud or on paper, students were and are judged by the number of facts they recognize, memorize and then insert into the approved format, which is also true of today’s essays, exams, and tests, and even in multiple-choice machine-scored exams.

But what of those urgent articles about AI making it impossible for teachers to know if their students really know? Short answer, they and we don’t, and we never did. And well, um… what do we mean by “know”? By the time I was 40 I had completely forgotten even the course titles of at least a quarter of those I attended on my way to my degree. By the time I was 80, I was just beginning to get a grip on what Hume had to say. By this I mean that learning in the humanities is a gradual, messy, inefficient, continuing process, non-evaluable even by yourself, let alone anyone else. And yet, universities continue to tell us that this person is brilliant, and that one not so much, and most of the time they’re right.

Will AI and ChatGPD (and their no doubt more sophisticated successors) change the academic essay? Yes, but not much. There will be fake essays as there have been for a very long time, along with honours degrees attained by people without honour.

Leaving aside the verity of essays for a moment, the larger issue in North American universities is the headlong retreat from tests, exams, defences of essays, theses, and dissertations. Though the ghost of the viva persists in graduate seminars, watered down by the increased number of people in the room, unfortunately, professors can no longer demand that students “stand and deliver,” because it is feared that this might make an individual the focus of unwelcome attention — particularly if the experience involves being interrupted, questioned, criticized, or graded. In universities where these concerns have been elevated to policy, evaluation is no longer acceptable lest sensitive souls be traumatized. Consequently, students offer “their truth” for immediate and uncritical acceptance and approval. For some pedagogues, this may be a comforting departure from the competitive world of marks, exams, evaluations and hierarchies of excellence, but “my truth” is very distinct from “truth” in “the whole truth and nothing but the truth” of the witness stand, where empiricism rules as much as any judge. And I’m pretty darned sure it isn’t “MY truth” that has long been featured on universities’ mottos and convocation addresses.

It seems inevitable that we will continue to speed up the academic process, thereby reducing both rote learning and formal essays featuring arcane (and variable) standards of footnoting and bibliography. We have the technology. Today’s electronic books and essay collections allow a student to copy words, phrases, sentences and paragraphs and paste them into their essays. No longer is it necessary for them to flip through the pages of half a dozen books open on one’s desk, consult their bibliographies and footnotes, check the date and edition on the flyleaf, ensure that the commas, parentheses, colons, upper and lower cases all follow the approved academic format. On-line sources allow words, phrases, and sentences to be cut and pasted into an essay, complete with fully-prepared citations ready for footnotes or bibliographies. Cut, paste, Bob’s your uncle. And when the essay arrives in the professor’s or marker’s inbox, the whole process can be deconstructed and reverse engineered by an app designed to root out plagiarism. Thinking is as optional as is reading the original texts. All can be done electronically by those who aspire to become the tenured cognoscenti.

Instead of the personal essay of yore (which I argue never really happened except to the exceptional few) we will still have the research essay with every concept, principle, deduction or factoid carefully referenced to its origin. The more serious flaw in this brave new essay-writing world lies not in the technology or how it is used, but that increasingly the essay is written totally within the framework of that particular aspect of that specific discipline, as if nobody outside those limited confines ever wrote anything of significance. Sociologists cite only sociology texts; psychologists focus exclusively on the work of other psychologists, those who teach literature refer only to literary critics. When this foolishness thrives, scholarly activity diminishes to skirmishes among increasingly recondite schools of thought within the parameters of the various disciplines.

I believe, that is, “it is my truth,” that the good deed of a genuine essay that wrestles sense out of a problem will still outshine glossy constructs by AI and Chatbot. The spoken words of an honest seminar presentation will compete with the glib grad who leads his once-a-term seminar without having read the books he talks about. The student who integrates thought across the artificial divides between courses, disciplines, and faculties will still be at university, whether recognized or not. Some will write books and articles that won’t appear in preferred journals and academic presses. Some will publish on Twitter, SubStack, or the like. Some will self-publish. Life, learning, and larceny will go on.

I no longer have to mark essays. If I did, the question I’d ask a student who has offered me what I suspect is a Chatbotted essay is, “Have you read it?”
