With all the current concerns about rogue and mis-aligned AI, and about how we've made essentially zero progress on making sure that AI is safe and trustworthy, NOW you want to put backdoors in encryption algorithms? We should be doing everything we possibly can to make our systems more secure, not less.
This type of policy was terrible when they first thought of it. Now it's outright negligent and dangerous.
There are people in the background that are benefiting from all this and it seems to me that its not limited to just one country. Someone knows that weakening all of these systems globally has a lot to gain.
