AI Can't Replace Education
Credit - Tingting Ji—Getty Images As commencement ceremonies celebrate the promise of a new generation of graduates, one question looms: will AI make their education pointless? Many CEOs think so. They describe a future where AI will replace engineers, doctors, and teachers. Meta CEO Mark Zuckerberg recently predicted AI will replace mid-level engineers who write the company's computer code. NVIDIA's Jensen Huang has even declared coding itself obsolete. While Bill Gates admits the breakneck pace of AI development is 'profound and even a little bit scary,' he celebrates how it could make elite knowledge universally accessible. He, too, foresees a world where AI replaces coders, doctors, and teachers, offering free high-quality medical advice and tutoring. Despite the hype, AI cannot 'think' for itself or act without humans—for now. Indeed, whether AI enhances learning or undermines understanding hinges on a crucial decision: Will we allow AI to just predict patterns? Or will we require it to explain, justify, and stay grounded in the laws of our world? AI needs human judgment, not just to supervise its output but also to embed scientific guardrails that give it direction, grounding, and interpretability. Physicist Alan Sokal recently compared AI chatbots to a moderately good student taking an oral exam. 'When they know the answer, they'll tell it to you, and when they don't know the answer they're really good at bullsh*tting,' he said at an event at the University of Pennsylvania. So, unless a user knows a lot about a given subject, according to Sokal, one might not catch a 'bullsh*tting' chatbot. That, to me, perfectly captures AI's so-called 'knowledge.' It mimics understanding by predicting word sequences but lacks the conceptual grounding. That's why 'creative' AI systems struggle to distinguish real from fake, and debates have emerged about whether large language models truly grasp cultural nuance. When teachers worry that AI tutors may hinder students' critical thinking, or doctors fear algorithmic misdiagnosis, they identify the same flaw: machine learning is brilliant at pattern recognition, but lacks the deep knowledge born of systematic, cumulative human experience and the scientific method. That is where a growing movement in AI offers a path forward. It focuses on embedding human knowledge directly into how machines learn. PINNs (Physics-Informed Neural Networks) and MINNs (Mechanistically Informed Neural Networks) are examples. The names might sound technical, but the idea is simple: AI gets better when it follows the rules, whether they are laws of physics, biological systems, or social dynamics. That means we still need humans not just to use knowledge, but to create it. AI works best when it learns from us. I see this in my own work with MINNs. Instead of letting an algorithm guess what works based on past data, we program it to follow established scientific principles. Take a local family lavender farm in Indiana. For this kind of business, blooming time is everything. Harvesting too early or late reduces essential oil potency, hurting quality and profits. An AI may waste time combing through irrelevant patterns. However, a MINN starts with plant biology. It uses equations linking heat, light, frost, and water to blooming to make timely and financially meaningful predictions. But it only works when it knows how the physical, chemical, and biological world works. That knowledge comes from science, which humans develop. Imagine applying this approach to cancer detection: breast tumors emit heat from increased blood flow and metabolism, and predictive AI could analyze thousands of thermal images to identify tumors based solely on data patterns. However, a MINN, like the one recently developed by researchers at the Rochester Institute of Technology, uses body-surface temperature data and embeds bioheat transfer laws directly into the model. That means, instead of guessing, it understands how heat moves through the body, allowing it to identify what's wrong, what's causing it, why, and precisely where it is by utilizing the physics of heat flow through tissue. In one case, a MINN predicted a tumor's location and size within a few millimeters, grounded entirely in how cancer disrupts the body's heat signature. The takeaway is simple: humans are still essential. As AI becomes sophisticated, our role is not disappearing. It is shifting. Humans need to 'call bullsh*t' when an algorithm produces something bizarre, biased, or wrong. That isn't just a weakness of AI. It is humans' greatest strength. It means our knowledge also needs to grow so we can steer the technology, keep it in check, ensure it does what we think it does, and help people in the process. The real threat isn't that AI is getting smarter. It is that we might stop using our intelligence. If we treat AI as an oracle, we risk forgetting how to question, reason, and recognize when something doesn't make sense. Fortunately, the future doesn't have to play out like this. We can build systems that are transparent, interpretable, and grounded in the accumulated human knowledge of science, ethics, and culture. Policymakers can fund research into interpretable AI. Universities can train students who blend domain knowledge with technical skills. Developers can adopt frameworks like MINNs and PINNs that require models to stay true to reality. And all of us—users, voters, citizens—can demand that AI serve science and objective truth, not just correlations. After more than a decade of teaching university-level statistics and scientific modeling, I now focus on helping students understand how algorithms work 'under the hood' by learning the systems themselves, rather than using them by rote. The goal is to raise literacy across the interconnected languages of math, science, and coding. This approach is necessary today. We don't need more users clicking 'generate' on black-box models. We need people who can understand the AI's logic, its code and math, and catch its 'bullsh*t.' AI will not make education irrelevant or replace humans. But we might replace ourselves if we forget how to think independently, and why science and deep understanding matter. The choice is not whether to reject or embrace AI. It's whether we'll stay educated and smart enough to guide it. Contact us at letters@

NHS set for boost of up to £30bn as other budgets feel squeeze
The NHS is expected to receive a funding boost of up to £30 billion in the spending review next week at the expense of other public services. The Department of Health is set to be handed a 2.8% annual increase in its day-to-day budget over a three-year period. The cash injection, which amounts to a rise of about £30 billion by 2028, or £17 billion in real terms, will see other areas including police and councils squeezed, The Times newspaper reported. Sir Keir Starmer has pledged to ensure that by the next election 92% of patients in England waiting for planned treatment are seen within 18 weeks of being referred. Latest NHS data suggests around 60% of people are currently seen in this time and figures released last month showed the overall number of patients on waiting lists had risen slightly from 6.24 million to 6.25 million. Chancellor Rachel Reeves has acknowledged that she had been forced to turn down requests for funding in a sign of the behind-the-scenes wrangling over her spending review. She insisted the blame for the tight economic situation lay with the Conservatives rather than her rigid rules on borrowing and spending. The Chancellor said despite a £190 billion increase in funding over the spending review period 'not every department will get everything that they want next week and I have had to say no to things that I want to do too'. On top of the increase in day-to-day spending, funded in part by the tax hikes Ms Reeves set out in her budget, looser borrowing rules will help support a £113 billion investment package. Economists have warned the Chancellor faces 'unavoidably' tough choices when she sets out departmental spending plans on June 11. The Institute for Fiscal Studies (IFS) think tank said defence and the NHS will dominate the review, raising the prospect of cuts to other unprotected departments.

The Best Tech Gifts for Father's Day 2025
Getting a gift for Father's Day (reminder: it's Sunday, June 15) is no easy task. What more could the dad in your life need other than your unconditional love? Turns out, physical gifts—preferably something useful or entertaining—are exactly what he needs to escape the hellscape that is our current timeline. Like we did for Mother's Day, we've curated a selection of the finest tech to get your favorite dad. With options for budgets under $100, under $300, under $500, and over $500, we're sure pops will like something from this list. Gifts Under $100 Anker 6-Foot USB-C Cable ($10) Nothing screams 'man of the house' like a 6-foot USB-C cable that can probably reach any outlet from the couch. For $10, you get two of 'em. Gotta keep the phone charged up when the commercials on the big screen hit. Buy at Amazon 8BitDo USB Wireless Adapter 2 ($20) It'll feel wrong at first to use a PS5 controller to play Xbox and vice versa, but it beats buying a completely new gamepad when you can just pair existing ones to your consoles using this USB dongle. The 8BitDo USB Wireless Adapter 2 even works with Switch, so dad can play Super Smash Bros. Ultimate with a PS5 or Xbox controller. Buy at Amazon Apple in China: The Capture of the World's Greatest Company ($30) Whether dad loves Apple or hates it, the company's sheer scale producing devices like the iPhone and iPad unexpectedly gave birth to China's technology scene and helped give rise to its largest Asian competitors such as Xiaomi and Huawei. Apple in China is a fascinating dive into how Apple's growth has made the world go round. Buy at Amazon Clair Obscur: Expedition 33 ($50) It's the talk of the gaming scene for good reason. Clair Obscur: Expedition 33 offers a feast for the eyes and ears, and a wonderful story wrapped in gameplay that feels new while scratching the itch of any dad still nostalgic for early Final Fantasy titles. Buy at Amazon Arcs ($60) Leder Games' Arcs is the kind of board game that does so much in such a small space. It's a trick-taking conquest game about gaining space supremacy in the vein of 4X games on PC. If you want to make it extra spicy, also buy the Blighted Reach expansion to connect multiple games into epic, multi-session storylines. Buy at Amazon Anbernic 34XXSP ($67) Anbernic's latest Game Boy Advance SP mimic is the kind of device that will put a smile on the face of any dad who grew up with a Game Boy in tow. The 34XXSP is powerful enough to play most games from early handhelds, and even a select few games from the N64 or Dreamcast era. Buy at Anbernic SETI: Search for Extraterrestrial Intelligence ($70) SETI: Search for Extraterrestrial Life is one of those games that will get both the space-loving and mechanics-minded dads excited to sit at the table with you. It's a game that will run for several hours, but it ends with such an epic climax that everyone will be jonesing for another round anyway. Buy at Amazon Xbox Design Lab Controller ($80) That skin oil-worn controller he's using to play Xbox may work just fine, but that doesn't mean he wouldn't love an upgrade. Microsoft's Design Lab is full of unique customization options—from colors to patterns to grips and more. Buy at Xbox Gifts Under $300 Backbone One ($100) A quality mobile controller may be the perfect gift if he has ever complained about aching thumbs while trying to play a game on a phone. Our current choice remains the Backbone One, but if you want to spend more, the Backbone Pro is a good upgrade with tighter controls. Buy at Amazon Govee Gaming Pixel Light ($120) Your dad deserves to jazz up his decor beyond bland paintings you can find at a thrift shop. The Govee Gaming Pixel Light lets the man in your life add his favorite 8-bit art (32×32 pixels) to his wall. Buy at Amazon Razer Pro Click V2 Vertical Edition ($120) Logitech's Lift is the go-to for vertical mice, but if your dad wants one for gaming, Razer's Pro Click V2 Vertical is the only way to go. Not only does it come with a more ergonomic design, but it also has more programmable buttons, faster polling rates for gaming, and RGB—gotta have RGB for dad to prove he's a real gamer. Buy at Amazon Nothing Ear ($130) There are a lot of wireless earbuds out there, but not everyone (dads included) is okay with defaulting to AirPods. Nothing's Ear, with its ceramic drivers, is fantastic for a dad who needs great audio with a style that's just a little bit different than most. Buy at Amazon Klipsch One Plus Premium ($170) Without making any assumptions about your dad, there's a chance that he may appreciate tech that's a little more analog. Klipsch's Bluetooth speaker brings great sound but also a slick mid-century design with knobs to boot—a design that combines modern tech with a vintage look. Buy at Amazon Lego Mario Kart ($170) What better way to spend time with a dad than over a Lego set? Even better is when that Lego set is a giant Mario riding a go-kart. 'It's-a-me-Mario!' voice not included. Buy at Lego Shun Classic Chef Knife ($170) This isn't the most high-tech product on this list, but it may be among the most practical. We can say with conviction that dad will never struggle with carving a bird ever again if you give the gift of Japanese steel. Buy at Macy's Polaroid Flip ($200) The Polaroid Flip is all nostalgia wrapped in a retro veneer, and it's now one of the better ways to take full-size instant photos at home. The camera is a hefty device, so dad may feel like a big, strong man lugging it around. Buy at Best Buy Flipper Zero ($200) The hardware-hacking dad in your life interested in his next DIY project would be absolutely thrilled to have the Flipper Zero. It's a signal multitool that can connect with various RFID and other radio protocols, plus the GPIO pins and custom firmware can be used to create a whole host of interesting use cases. Buy at Flipper Zero Boox Palma ($246) Kindles and Kobo e-readers are great for reading ebooks, but they don't fit into pockets. The Boox Palma is exactly the solution—a phone-sized e-reader that runs Android apps (though using it for anything more than ebooks is slow AF) that dad can actually grip with one hand. Buy at Amazon Meater Pro XL ($280) Grill dads who don't want to stand by the open flame constantly for every cookout will appreciate the Meater Pro XL. The device's four smart meat probes will let him monitor the temperatures and finish times for multiple meals through a single app, which means no more sprinting back and forth between oven and grill. Buy at Amazon Gifts Under $500 Meta Quest 3S ($300) Has your dad ever expressed any interest in VR, or even doing some at-home workouts? Set him up with the Quest 3S, and he won't need anything more. Buy at Amazon Philips Hue Play Sync Box ($334) If your dad needs an upgrade to his entertainment system, Philips' Hue Play Sync Box has him covered. This tiny box can coordinate the lighting of a movie with Hue smart lights and syncs TV content at 8K 60Hz and 4K 120Hz for a unique home theater experience. Buy at Amazon Google Pixel Watch 3 ($350) Everyone has an Apple Watch. Let dad feel different with the Google Pixel Watch. It tracks almost everything an Apple Watch does, including health and fitness, and the battery life is excellent. The only caveat is that it works with Android phones, not iPhones. Buy at Amazon Meta Ray-Bans ($350) Smart glasses might seem like an overboard gift if dad isn't tech-inclined, but Meta's Ray-Bans might be the right ratio of tech-to-style goodness. They have a classic look and are surprisingly nice for Bluetooth audio. Buy at Amazon Breville Paradice 9 ($395) Don't fault dad if his knife skills are subpar. Fortunately, a high-powered food processor like the Breville Paradice 9 can slice and dice just about any ingredient more evenly and faster. Technology saves time! Who'd have thunk it? Buy at Amazon Sony WH-1000XM8 ($448) Whether it's blocking out a crying baby or angsty teenager, Sony's latest WH-1000XM6 over-ear headphones deliver best-in-class active noise cancellation. Bonus points: they fold up neatly and come with a case that doesn't look like a bra (looking at you AirPods Max Smart Case). Buy at Amazon Gifts Over $500 Xreal One ($500) Maybe some lucky dads will get a $3,500 Apple Vision Pro for Father's Day, but if all dad needs is a pair of video glasses for watching Netflix and YouTube, Xreal's One is more than good enough and stupid easy to setup (just plug it into any device that supports USB-C video out). They're barely larger than a pair of sunglasses, the 1080p video is super sharp, and the screens even dim for a see-through effect. Buy at Amazon reMarkable Paper Pro ($680) If you're gonna get dad an e-reader and can splurge for the very best, the reMarkable Paper Pro is the one to get. It's got a color E Ink screen that's great for reading comics, supports a stylus for notetaking, and you can even get a keyboard folio case for it. Buy at Amazon
