Exactly if that is the case, it should also include technologies where data ownership lies with the users. After all data itself is a huge resource. One of the biggest reasons corporates could monopolise the platform because as users we only had our own data but no access to others data.

Maybe a consent mechanism to use other's data in privacy safe manner, where anyone can build their analytics models and people can choose which one to follow or choose. Seems like a interesting proposition.

But cryptobros are all about secondary markets. So as soon as you give permission to your data to an entity they'll copy it off-chain (you can't stop them if they can read it) and bundle it up for resale.

All this does it flip the problem. Instead of a singular entity that "owns" the data, everyone owns it. So instead of having no privacy from the singular entity with a wide reach you've got no privacy from anyone.

That's why not giving them ability to copy data, allow them to use that data only on your device and send aggregated information back. So they cannot copy the data

So they are going to run code at your home instead of using data directly. Maybe I'm missing something but this sounds bit naive to me. Most of those crypto solutions sounds just like detour with similar result in the end.

Like you can have decentralized web now, you can host your video on your server. Maybe even p2p. Just the reach would be probably minimal. And you can have your own bitcoin wallet. I was downloading chain to my wallet ten years ago and it was slow. Most people will chose some centralized service even for crypto.

I was thinking along ML. How analytics and ML happens on user data which is stored on data silos. For example, twitter has data about all our posts and interactions and uses that data to build recommendation models which it monetizes as to who comes on top.

In decentralized world, everyone can build their models, host them and train them on user data. But since, I wouldn't want my data to be used for any other purpose, I don't want them to make a copy of that data. So they send their models (after taking my consent) to my device, train it locally and send the aggregated model back.

You're just describing signing tokens which has been around for decades with smart cards. There's no need for a blockchain to be involved in that process. It just makes it slower, expensive, and public.

If you want some personal data to show up somewhere be it a name or avatar it has to leave your device. At that point someone can and will copy that data. If there's value with associating that data with your activity someone will do it.
