You are complaining about the photo monitoring functionality, which happens 100% on device. You can confirm this very easily by monitoring the app’s network activity when you receive an image. Android System SafetyCore does a lot more things than photo monitoring, one of which is providing emergency location data (ELS). This is required by law in the EU, India, and the USA.
The same people who buy ATX form factor x86? The only thing making these platforms different is software support, which is getting better for RISC-V everyday. You wouldn’t buy a RISC-V computer today for high performance gaming or scientific computing, but it definitely works as a general purpose machine (web browsing, office apps, watching videos, etc.) This year shouldn’t see much progress in hardware since RVA23 just came out (maybe some RVA22 + V), but you can expect some nice things to come out 2026-2027 since now you have all you need to build a competent RISC-V CPU.
