I'm also betting on Graphene. Been able to get by with a profile without Play Services, thankfully my bank doesn't require it, but if they ever do (or the new integrity bullshit), I'm immediately switching banks to one that doesn't.
That's the only app I need on my phone, anything else I can get without if they require it.

Remember that (I think) C++ race condition in RTG software, that killed people with something like 0.0001% probability and it was a huge deal and a reason to immediately retire the devices (or maybe just fix the bug, the point is that in medical, it's super important to have a high success chance)?
I'm sure AI doing diagnosis will be able to get to a higher success chance, lol.
EDIT: From a quick search, it looks like mis-diagnosis chance in doctors is around 10%. I still don't think AI can do better.
