META AND YANDEX ARE DE-ANONYMIZING ANDROID USERS' WEB BROWSING IDENTIFIERS

Meta and Yandex Are embedding tracking code into millions of websites to de-anonymize visitors. The code abuses legitimate Internet protocols, causing browsers to send unique identifiers to native apps installed on a device. It bypasses core security and privacy protections provided by the Android operating system and the browsers that run on it. Currently, the only way to protect against the tracking is to refrain from installing the Facebook, Instagram, or Yandex apps on Android devices.

The external world puts a speed limit on AI development. Systems need to be tested in real-world conditions to encounter failures they can learn from. Edge cases can be learned, but that will often need to happen while doing real tasks. This creates a speed limit in two ways: you have to wait to collect that data and some people may be reluctant to try out the technology while the system works out its bugs.
