I. Current state of AI: The fact of data 'naked running'.
In the morning, your phone's voice assistant reminds you: 'It's going to rain today, you should take an umbrella' — it has obtained your geographic location, which you agreed to, because if you disagreed, you wouldn't be able to use it at all;
The shopping app pushes products you discussed last night — it eavesdropped on the conversation! In the future of big data streaming, you will only see things you like, which also fosters each of our narcissism and closes off other possibilities;
Norm: The so-called 'user agreement' is like a book of heavenly scriptures, no one reads it carefully and just clicks 'agree';
II. FHE homomorphic encryption — another Schrödinger's box.
It's like: putting your personal data in a box, whether it's for AI companies, medical systems, DeFi, or gaming; Agents can support calling the information provider to complete analysis without seeing your name, address, etc., yet still support analysis of your health data, gaming preferences...
FHE redefines 'authorization': you no longer 'give up' data, but rather 'rent' the right to use the data (the original data always remains in your hands) — just like renting a house to tenants, where different tenants can only access specific rooms, but the keys always remain in your hands.
III. The fantasy of encryption enthusiasts: Everyone is the master of their own data.
As a believer in cryptographic technology, I believe FHE will trigger a revolution:
Data rights revolution: Medical records, social dynamics, consumption habits, are no longer 'free resources' for tech giants, but rather priced and traceable personal assets, which you can 'rent' to AI companies for a fee;
Decentralized AI revolution: AI models are jointly trained by global users, with no centralized servers and no data monopolies; AI truly belongs to all humanity;
As an ordinary person, we may not understand code, but we can support privacy protection technologies; as encryption enthusiasts, we should shout: 'Let encryption serve reality, not just wealth investment but also the future of technology!'
