It's worth noting that this is the much maligned commission acting as it often does at the behest of the member states. Speculation about what exactly will be proposed should be avoided but the wonks at the commission will be aware of the impossibility of getting backdoors for true end-to-end encryption. And the ECJ has already ruled in favour of individual's right to privacy. So this sounds like a stick to beat the tech companies with for better cooperation: get those AIs to do something useful like monitoring phones and reporting any "suspicious" activity.
If end-to-end encryption becomes illegal, which I very much doubt, it's hardly likely to stop anyone who is already breaking, or considering to break, the law…
