At least you can understand how others justify their continued use based on the lack of no perfect alternative, even in the face of the current solutions imperfections.

My understanding is that, in broad strokes... Aurora acts like a proxy or mirror that doesn't require you to sign in to get Google Play Store apps. It doesn't provide any other software besides what you specifically download from it, and it doesn't include any telemetry/tracking like normal Google Play Store would. microG is a reimplementation of Google Play services (the suite of proprietary background services that Google runs on normal Android phones). MicroG doesn't have the bloat and tracking and other closed source functionality, but rather acts as a stand-in that other apps can talk to (when they'd normally be talking to Google Play services). This has to be installed and configured and I would refer to the microG github or other documentation. GrapheneOS has its own sandboxed Google Play Services which is basically unmodified Google Play Services, crammed into its own sandbox with no special permissions, and a compatibility layer that retains some functionality while keeping it from being able to access app data with high level permissions like it would normally do on a vanilla Android phone.

ChatGPT is not a doctor. But models trained on imaging can actually be a very useful tool for them to utilize. Even years ago, just before the AI “boom”, they were asking doctors for details on how they examine patient images and then training models on that. They found that the AI was “better” than doctors specifically because it followed the doctor’s advice 100% of the time; thereby eliminating any kind of bias from the doctor that might interfere with following their own training. Of course, the splashy headline “AI better than doctors” was ridiculous. But it does show the benefit of having a neutral tool for doctors to utilize, especially when looking at images for people who are outside of the typical demographics that much medical training is based on. (As in mostly just white men. For example, everything they train doctors on regarding knee imagining comes from images of the knees of coal miners in the UK some decades ago)
