When privacy technologies can automatically enforce limited use, the time to study another organization's data collapses from days/months to minutes; from one organization to thousands.
Studying data at another organization is hard because of the bureaucracy/cost involved manually enforcing limited use. For example, accessing data in a hospital can take months and require working onsite.
When PETs are combined in a data-hosting web server capable of automating the enforcement of data-use policies, a new internet is born. Researchers will study data remotely across thousands of these servers/orgs with instant results. The right open-source, public-good infrastructure will maximize scale and impact.
