The future is going to be a personalised approach. Tailoring medical curricula involves adapting the educational content to meet the specific needs and preferences of individual learners. This approach recognises the diverse learning styles, backgrounds, and goals of medical students, allowing for a more personalised and effective learning experience.^[31]

Adaptive assessments in medical education use technology, often powered by AI, to tailor the evaluation process based on individual learner performance. These assessments adapt in real-time, providing targeted questions and feedback to address specific areas of strength or weakness.^[32]

Individualised learning pathways involve creating a unique educational journey for each student based on their progress, interests, and career goals. By leveraging technology and data analytics, medical education can design pathways that optimise learning efficiency and better prepare students for their chosen medical specialities.^[33]

AR and VR technologies offer immersive experiences for anatomy education, allowing medical students to explore 3D anatomical structures in a virtual environment. This facilitates a more interactive and engaging learning experience compared to traditional methods.^[34] AR and VR enable the creation of virtual patient scenarios, providing medical students with opportunities for realistic and risk-free patient interactions. These simulations can mimic a variety of medical conditions, enhancing clinical decision-making and communication skills.^[35] AR and VR technologies play a crucial role in surgical simulations, offering realistic virtual environments for practising surgical procedures. These simulations enhance surgical skills, hand-eye coordination, and decision-making in a controlled setting for budding surgeons.^[36]

We acknowledge that while technology offers numerous advantages, it also presents certain caveats that warrant consideration. Specifically, the economic burden incurred by colleges and students in implementing and accessing technology-enhanced resources is a significant concern. The costs of acquiring equipment, software licences, and training faculty on new technologies can strain institutional budgets and place financial pressure on students. Moreover, the digital divide exacerbates inequalities, with some students lacking access to technology or reliable internet connections. Overreliance on technology risks depersonalising the learning experience, potentially diminishing interpersonal skills and teamwork abilities crucial for effective healthcare practice.

While it is undeniable that newer technologies and teaching methods play a crucial role in enhancing medical education and preparing students for the complexities of modern healthcare, it is equally important not to overlook the invaluable lessons learned through bedside teaching. Bedside teaching offers medical students the unique opportunity to directly interact with patients, observe clinical presentations, and develop important clinical skills such as history-taking, physical examination, and patient communication. These experiences are essential for fostering empathy, clinical reasoning, and professional identity formation, which are central to the practice of medicine.

Additionally, concerns regarding the privacy and security of sensitive patient and student data arise with the integration of technology. There is also a risk of skill gaps and technological obsolescence, as students may become overly dependent on rapidly evolving digital tools. We acknowledge that we have no personal experience of using a number of these technological advances as it is a narrative review. However, balancing the benefits of technology with these drawbacks is essential to ensure that medical education remains comprehensive and equitable to the needs of students and patients alike.

The future is going to be an integration of AI. This will include intelligent Tutoring Systems for Personalised Learning, AI-Assisted Diagnosis and Decision-Making and Virtual Patient Simulations for Practical Experience (Table 2).
