It would be the solution to phone obsolescence. This concept, paired with project treble would allow us to run our phones for as long as possible. Want a screen with more pixels? Just install one. Phone getting behind on specs?Change the cpu or add ram. Want a better camera? Just get a new one. At some point, the chassis would need to be replaced, but even then, you could reuse some of your installed conponents. It would be so awesome.
It’s not just a matter of discomfort for something new, but at something highly dangerous. Deepfakes have several bad and disturbing use cases, like itentity theft, sexual exploitation, marketing abuse, political manipulation, etc. In fact, I hard to find a significant good use of such technology.
