Context: Chat Control 2.0: EU governments set to approve the end of private messaging and secure encryption
"By making a minor concession EU governments hope to find a majority next week to approve the controversial 'chat control' bill. According to the proposed child sexual abuse regulation (CSAR), providers of messengers, e-mail and chat services would be forced to automatically search all private messages and photos for suspicious content and report it to the EU. To find a majority for this unprecedented mass surveillance, the EU Council Presidency proposed Tuesday that the scanners would initially search for previously classified CSAM only, and even less reliable technology to classify unknown imagery or conversations would be reserved to a later stage. The proposed „deal“ will be discussed by ambassadors tomorrow and could be adopted by ministers next week."
With quantum computing around the corner that key is useless. So not only is my data then shared with the EU, china and US will also have a little look
That's very speculative though. We don't know yet the effect how large scale quantum computing will have on encryption.
Fun fact: Quantum computers already exist and you can play around with one for free*: https://www.ibm.com/quantum
