If you’re a regular internet user the Personal Data Storage paradigm won’t move your data from the cloud to your personal computer. Most people will still rely on an institutional cloud service, but instead of data-banking with a shareholder-controlled corporation people’s data can be entrusted to the equivalent of member-owned credit unions for data storage.
Yeah I would prefer to move my data from the cloud to my personal computer. With fully automated cloud-based end-to-end encrypted backups, of course. Even web apps have good access to local storage now. If I want to share my personal data with someone, I can send it to them.
I’m sure there are a few applications where something more complicated is required. Neither lemmy comments nor biometric data from a “smartwatch” are among them.
