Every Qingming Festival, cemeteries and columbaria across Hong Kong are packed to capacity. Faced with the city’s acute land shortage, the government has actively promoted green burial options such as sea scattering and garden ash scattering.
Yet beyond scattering ashes at sea or into soil, the way we honour the departed is undergoing profound technological transformation. From cremation stones, made by crystallising cremated remains, to AI and QR-code digital memorials, high-tech remembrance is reshaping the emotional bond between the living and the deceased.
Trend 1: Turning Cremated Remains into Cremation Stones
Apart from interment in columbaria or ash scattering, Cremation stones (also known as Memorial Crystals) have grown rapidly in popularity among Chinese communities, originating in South Korea and Japan.
Cremated ashes are melted at nearly 2000°C. Silica, calcium and phosphorus naturally present in the ashes recrystallise to form hundreds of dense stone fragments. Resembling pebbles or pearls, Cremation stones are hard, moisture-resistant, non-corrosive and colourfast, enabling preservation over long periods. More affordable than memorial diamonds, they can be produced within hours. Families may keep them in a memorial box at home or set them into jewellery.
Parting Stone, a New Mexico-based firm in the United States, is a globally recognised manufacturer of solidified ash memorials. Cremated remains are purified, blended with natural binders, then heated in a high-temperature furnace close to 2000°C to form a solid memorial stone.
Trend 2: AI Enables Digital Immortality for the Departed
Generative AI technology has made conversations with the deceased possible. With authorisation, large language models can be trained using the departed person’s voice recordings and social media posts, replicating their tone of speech, personality and preferences. Family members may converse with this AI representation of their loved one within an online memorial space.
Some older adults record hundreds of Q&A sessions covering their life stories, philosophy and messages for descendants while still alive. At funerals or future memorial services, the AI system responds in real time to mourners’ questions, delivering pre-recorded answers as if the deceased were responding in person.
In August 2022, Marina Smith MBE “attended” her own funeral in AI virtual form. Working with StoryFile’s AI Conversational Video technology during her lifetime, Marina allowed mourners at her service to pose questions directly to a screen; the AI interpreted queries and replied instantly.
South Korean firm DeepBrain AI offers the Re;memory service. Combining 4K high-resolution filming and voice cloning technology, it creates a life-sized digital replica of terminally ill individuals. After their passing, family members may hold lifelike real-time conversations in a dedicated AI memorial room.
Trend 3: AR and QR Code Technology
Technology is not intended to fully replace traditional remembrance.
The Food and Environmental Hygiene Department(FEHD)’s Infinite Memories online memorial platform embeds QR codes on physical columbarium niches or memorial garden plaques. Scanning the code pulls up the deceased’s biography, audio‑visual records and family tree.
Spot Message is an app developed by a stonework company(Ryoshin Sekizai りょうしんせきざい) in Chiba, Japan, featuring AR tombstone functions. Using GPS positioning and augmented reality, bereaved relatives visit the grave site, point their smartphone camera at the monument, and see pre-recorded 3D virtual avatars or hear voice messages from their loved one, saying for example, “Thank you for coming to see me.”
Tradition and Technology: Ethical and Psychological Considerations
While high-tech memorialisation brings convenience and emotional comfort, it has sparked public debate:
- Can AI “reconstruction” prolong grief? Psychologists warn over-reliance on AI conversations may trap people in denial of death, hindering healthy acceptance of loss.
- Privacy and informed consent: Do family members have the right to train AI models using the deceased’s personal data without prior consent? This touches on dignity and digital privacy rights for the deceased.
- Intent matters more than form. Older generations often hold the traditional belief that the deceased “should return to the earth”. New technological memorial options require communication and respect between seniors and their descendants.
Closing Remarks
The core of remembrance has remained unchanged through history: it is the living’s affection and tribute to those who have passed away. Whether using tombstones, ash scattering, Cremation stones or AI conversations, technology offers another avenue to keep love alive.
