Recently, Suzanne Bearne wrote an article for the BBC titled “Meet the 'doctors' who will talk to you whenever you like.†The piece touched on the rapid development of medical software and raised a key question: can technology truly replace human doctors? “How have you been feeling over the past month?†Joy asked. “This helps me understand your current state.†Joy conducted a deeper check with me, asking about my emotions—was I sad? Was I stressed? When I mentioned that life had been a bit overwhelming, Joy provided some practical tips on how to manage stress. Though Joy feels like a personal advisor or mentor, the conversation was actually between me and a chatbot. Thanks to artificial intelligence and machine learning, these systems can detect emotions and offer mental health support. All of this took place through Facebook Messenger. Welcome to the digital age of healthcare, where patients can consult doctors with just a few taps on their phones. Joy was created by Danny Freed after a close friend passed away by suicide. This tragic event inspired him to explore how technology could help people with mental health issues. “I realized we’ve recorded all the data and formulas related to physical health, but we neglected mental health,†he said. Joy encourages users to express their feelings and offers scientific advice and coping strategies. But is it really effective? Freed doesn’t overstate what Joy can do. “Joy isn’t a clinic or a treatment,†he explained. “It’s more like a friend or mentor.†To address concerns about credibility, he recently hired an expert in emotional disorders as a consultant. Since Facebook opened its Messenger platform to developers in 2016, over 100,000 chatbots now exist on the platform, many focused on health and mental wellness. One such example is Weobot, developed by Alison Darcy, a clinical psychologist from Stanford University. Weobot uses cognitive behavioral techniques to help users track their emotions and identify early signs of depression. As users interact with it, the bot learns and suggests ways to counter negative thoughts. While Joy is free, Weobot charges $39 per month after 14 sessions. Considering that traditional psychiatric care can cost between $30 and $200 per hour, digital assistants are becoming increasingly appealing. Dr. Ali Parsa, CEO of Babylon, a digital healthcare app, believes that mobile health solutions are here to stay. “We should treat healthcare like Google treats information—make it accessible to everyone, regardless of location or income, and put a doctor in your pocket,†he said. Babylon's team of scientists, engineers, and clinicians built a database using over 3 million medical cases. Using machine learning and natural language processing, the app provides symptom-based advice. “It can understand, infer, predict, and learn from real-world scenarios, much like a real doctor,†said Dr. Parsa. Users can also book appointments with real doctors or counselors through Babylon, starting at £25. Another digital health startup, Your.MD, has raised $10 million in funding. It works similarly to Babylon, offering personalized health insights based on user symptoms, medical history, and personal details. Its CEO, Matteo Berlucchi, claims, “Your.MD is better than real doctors—it has no bias and a super brain.†He believes that AI will soon outperform physicians in many diagnostic tasks. However, both Berlucchi and Parsa acknowledge that human doctors still have unique advantages. “They can see you, hear your breath, look into your eyes, check your ears, and perform blood tests,†Berlucchi noted. Many remain skeptical about medical software, especially since many apps lack proper regulation. Karen Taylor, director of the British Medical Solutions Center in Detroit, warns, “Patients shouldn’t rely entirely on software. There are situations where it simply can’t handle complex cases.†Richard Vautrey, acting chairman of the British Medical Association’s General Practice Committee, agrees. “While AI can process data and make diagnoses, trained doctors are still needed to interpret underlying conditions,†he said. Despite these concerns, medical software continues to evolve by learning from vast amounts of data. Claire Novorol, chief medical officer and co-founder of Ada, predicts that future versions of the app will integrate more data from lab results, genetic tests, and wearable devices. This will allow the system to track health trends and spot potential issues before they become serious. “Ada isn’t just a health assistant—it supports long-term monitoring and proactive health management,†she explained. She envisions a future where AI and doctors work together in a more collaborative way, enhancing patient care rather than replacing it.

Optical fiber connector is a detachable (movable) connection device between optical fiber and optical fiber. It connects the two end faces of optical fiber precisely, so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the impact on the system caused by its involvement in the optical link can be minimized. This is the basic requirement of optical fiber connector. To a certain extent, optical fiber connectors affect the reliability and performance of optical transmission systems.
