I have started companies before this one and sold some of them. This is the first time I have spent three years on a question rather than a product, and it is the only question I would have done that for.
The problem is not really technical, it is an accounting one. There is an enormous quantity of data in the world that would improve how medicine is practised, how risk is priced, how systems are built to fail safely — and almost none of it can be used, because using it means putting it inside a model that afterwards cannot say what it did with it. So it stays where it is, and everything it could have done goes unspent. Somewhere behind those doors are the applications nobody has reached yet, in fields that have never had a model trained on their own data because the data was never releasable.
Nobody holding that data is being careless. They are right to hold it under the conditions that exist. What is missing is the account that would make opening it defensible, and that account has to be built into how a model learns, because it cannot be recovered later.
I wanted to contribute a fact to this field rather than an opinion — measured, reproducible, checkable by anyone who cares to check it. That is why the mechanism gets published rather than kept back, and why every experiment regenerates from seed. If I am wrong, I would rather the field established that quickly.
