From classroom to campus: Sacred Heart seniors dive into AI and business ethics at St. John's.

From classroom to campus: Sacred Heart seniors dive into AI and business ethics at St. John's. * home * news * from classroom to campus: Sacred Heart seniors dive into AI and business ethics at St. John's. March 25, 2026 Eighteen seniors from Sacred Heart Academy (SHA) in Hempstead, NY, visited St. John's University's Queens, NY, campus on March 23 for an immersive day of learning centered on several of today's most pressing issues. Through a series of engaging lectures and discussions, students explored topics such as artificial intelligence (AI) and corporate and social responsibility, gaining firsthand insight into how these forces are shaping the future of business and society. "The partnership between SHA and St. John's is not new, it's just getting stronger," explained Jacqueline Grogan '90SVC, '95M.B.A., '01P.D., '10Ed.D., Associate Provost for Enrollment Partnerships and Engagement. "We share so much in common with SHA - their values match our values, SHA teaches their students the importance of giving back, and we teach our students the same." Before the presentations, the students learned about the University's mission. They enjoyed a short campus tour led by Student Ambassadors, which included a visit to St. Thomas More Church. "I loved seeing the mosaic inside the church and seeing how it tells the story of St. Vincent de Paul. It was really impressive," said Ava Reda, a student from Inwood, NY, who plans to study marketing in college. "I was surprised at how big the campus actually is. Even on a rainy day like today, it's just beautiful. I can only imagine what it's like when everything is in bloom." After their tour, the group assembled inside the William L. Munson Lecture Hall for a presentation by Max A. Hergenrother, Associate Dean, Technology and Pedagogic Innovation, The Lesley H. and William L. Collins College of Professional Studies, who led a discussion of the University's position on the hot-button topic of artificial intelligence. He explained that the University embraces the often-misunderstood technology. "At St. John's, we don't ban AI - we teach students how to use it responsibly, ethically, and effectively in the real world," he said. "We know AI is here, and we want students to use it responsibly so we can have a generation of innovators and leaders." Mr. Hergenrother announced that St. John's recently signed a partnership with Superhuman (formerly Grammarly), to develop a platform tailored to the ethical use of AI. Maciek Nowak, Ph.D., Dean, The Peter J. Tobin College of Business (TCB), added, "We want to make sure our students are as prepared as possible for what AI offers and add that human element - things like communication skills, presentation skills, and networking - which AI will not be able to replace." Building on this forward-looking approach to innovation and responsibility, the conversation turned to another area where St. John's is actively shaping the future of business education: ensuring that opportunity and representation evolve alongside emerging technologies. Daniel Napolitano, Assistant Dean, Student Services and Community Design, TCB, noted that while most business schools are still dominated by men, St. John's works to promote gender balance and economic equity at Tobin. "Our Vincentian mission is to serve the poor, elevate the underrepresented, and make sure access is granted to all," he explained. "It is very important to me personally and to our students that we have female faculty and that we have students who are having conversations about the industry and how to improve it." Later, the group attended a session on corporate and social responsibility led by Tobin's Ingrid D. Fray, D.M., Associate Professor of the Practice, MECO (Management, Entrepreneurship, Consulting, and Operations) Management. While the young women in attendance represented a wide range of academic interests, they found the content of the sessions strikingly relevant and deeply engaging. "Even though I plan to study biology, I think it's smart to have a solid understanding of business principles and ethics," explained Gabriella Sacco of Franklin Square, NY. "Whether you're paying your taxes or your mortgage, you don't want to rely exclusively on others to help you." For lifelong Red Storm fan Lila Lavelle of Rockville Centre, NY, the campus visit could not have come at a better time, as it happened only hours after the Men's Basketball team defeated Kansas on a last-second shot to reach the National Collegiate Athletic Association Division I Men's Basketball Tournament Sweet 16. "I've been coming to campus for basketball games since I was a little kid, so that win makes my visit today feel even more special," said Lila, whose grandmother, Mary Fascilla Craig '88SJC, attended the University. "As a Sacred Heart student, the fact that St. John's is also a Catholic school is very important to me." According to Kim Johnson, President of Sacred Heart Academy, the connection between the two institutions extends well beyond their shared Catholic identity and is rooted in a common commitment to forming students who lead with purpose. "At Sacred Heart Academy, our foundation is grounded in the mission of the Sisters of St. Joseph," said Ms. Johnson, who accompanied the students. "We strive to develop young women of courage, compassion, and commitment - students who excel academically while embracing a deep sense of service, giving back, and living lives of purpose. That mission closely aligns with the values of St. John's." That shared commitment to mission-driven education is reflected in the long-standing relationship between the two institutions, something Dr. Grogan has witnessed firsthand. "So many SHA students have attended St. John's University, and these women are strong, successful, proud alumnae of both institutions," she said. "I look forward to working with and welcoming back SHA's leadership and students to our campus."

Backlash prompts Grammarly to rethink 'expert review' feature.

Backlash prompts Grammarly to rethink 'expert review' feature. 19 March 2026 * homepage * > * news * > * business * > * backlash prompts Grammarly to rethink 'expert review' feature. Writing assistant software tool Grammarly has recently disabled its "Expert Review" feature following backlash from authors, journalists, and academics. Now it says it will 'reimagine' the feature, allowing experts to decide whether they want to participate in future artificial intelligence (AI) plans. Superhuman, the company behind Grammarly and other popular apps like Coda, said it has disabled the writing app's Expert Review, launched in August 2025, which offers "feedback inspired by subject-matter experts" to help writers craft arguments the same way experts would. "After careful consideration, we have decided to disable Expert Review as we reimagine the feature to make it more useful for users, while giving experts real control over how they want to be represented - or not represented at all," Ailian Gan, Superhuman's director of product management, told The Verge. "Based on the feedback we've received, we clearly missed the mark. We are sorry and will do things differently going forward." On March 11, Superhuman launched an inbox feature allowing writers to opt out of its experts review. However, the company later realized that the move wasn't enough. On top of that, CEO Shishir Mehrotra also issued an apology on LinkedIn, outlining plans to create a system where "experts choose to participate, shape how their knowledge is represented, and control their business model." Mehrota also stated that they take valid critical feedback from experts seriously, particularly concerning the potential misinterpretation of AI regarding their voices. "We hear the feedback and recognize we fell short on this. I want to apologize and acknowledge that we'll rethink our approach going forward...We deeply believe in our mission to solve the 'last mile of AI' by bringing AI directly to where people work, and we see this as a significant opportunity for experts," she said. "For millions of users, Grammarly is a trusted writing sidekick - ever-present in every application, ready to help. We're opening up this platform so anyone can build agents that work like Grammarly - expanding from one sidekick to a whole team." Do we need AI for writing and research? Over the years, AI has been gaining popularity, especially in writing and research, but a few critics still question its accuracy. In an October 2025 report by UNESCO, it claimed that the tech can copy humans' works, resulting in "creating flawless headlines, realistic images, and copying human voices." However, AI, according to UNESCO, could risk spreading misinformation, pointing out why Media and Information Literacy is still crucial today. "Large language models (LLMs) have an odd habit: they 'hallucinate.' They create information that sounds believable but is completely made up like fake quotes, invented sources, false statistics. Here's the worrying part: these errors aren't rare mistakes. They're built into how these systems work. AI models are designed to be good at answering questions. When they're unsure, they guess because guessing actually helps their performance," it said. "The danger isn't simply that AI can make mistakes, but that these mistakes can mislead citizens, sway leaders, and shape public opinion - all while appearing entirely credible." In November 2025, the University of Cambridge published a research paper stating that 51% of U.K. novelists believe AI could eventually replace their work in fiction. Nearly 59% say their work has already been used to train LLMs without their permission or compensation. In addition, 39% reported loss of income linked to generative AI, and 85% are expecting to further reduce their earnings. In order for artificial intelligence (AI) to work right within the law and thrive in the face of growing challenges, it needs to integrate an enterprise blockchain system that ensures data input quality and ownership - allowing it to keep data safe while also guaranteeing the immutability of data. Check out CoinGeek's coverage on this emerging tech to learn more why Enterprise blockchain will be the backbone of AI. Watch: AI is a double-edged sword

Superhuman Disables Controversial Grammarly AI Feature

Superhuman disables controversial Grammarly AI feature. Superhuman has disabled Grammarly's "Expert Review" feature that impersonated real writers and academics, following outrage and a class-action lawsuit against the company. The tool, launched in August, used AI to generate feedback credited to specific experts without their consent. Living authors expressed outrage, leading to a class-action lawsuit against Superhuman. CEO Shishir Mehrotra announced the decision to suspend the feature on LinkedIn on March 11, 2026. The controversy highlights the legal risks of AI systems that scrape personal data to create commercial products. The feature relied on publicly available information from third-party LLMs to mimic experts. It displayed names of both living and deceased individuals alongside a disclaimer. The disclaimer stated the references were for informational purposes only and did not imply endorsement. The feature allowed users to select experts based on subject matter. It included figures ranging from scientists to fiction authors. Users received feedback generated to appear as if it came from these individuals. The tool did not seek permission from the people named. Mehrotra stated the agent was designed to help users discover influential perspectives. Grammarly initially attempted to mitigate backlash by allowing writers to opt out of the platform. This response failed to satisfy many critics. A class-action lawsuit is currently underway against Superhuman regarding the tool. Mehrotra said the company is reassessing the feature before any potential reintroduction. Grammarly is a widely used writing assistant. Superhuman, primarily an email productivity app, acquired Grammarly in a major industry deal. The acquisition positioned Superhuman as a broader productivity platform. The company faces ongoing scrutiny regarding its use of AI and user data.

Grammarly CEO claims firm processes 100B LLM calls weekly, generates $700M revenue

Superhuman CEO Shishir Mehrotra says Grammarly is widely misunderstood, functioning not as a spell-checker but as infrastructure for AI agents across numerous applications. The company now anchors a four-product AI suite. Grammarly processes over 100 billion large language model calls weekly for 40 million daily users, generating more than $700 million in revenue. Its latest product, Superhuman Go, enables enterprises to deploy AI agents directly where employees work. The company's scale demonstrates significant commercial traction in the AI infrastructure space, positioning it as a critical platform for agent deployment rather than a simple writing tool.

Grammarly offers 'expert' AI reviews from authors dead and alive — without permission

Grammarly, now part of the rebranded Superhuman company, has introduced an "expert review" feature that offers AI-generated feedback styled after real authors and academics—both living and deceased. Users can receive critiques from simulated versions of figures including Stephen King, Neil deGrasse Tyson, Carl Sagan and editor William Zinsser. The feature provides no actual involvement from these individuals, with a disclaimer stating references are "for informational purposes only" and don't indicate affiliation or endorsement. The company says the AI examines users' writing and surfaces expert content to help shape their work, pointing users towards influential voices. The legality of training AI on these individuals' works remains unclear and has sparked criticism. University of Birmingham professor Vanessa Heggie called the practice "obscene", accusing the company of trading on names and reputations without permission.
