Mostly concerned with the billions of embedded devices, everything else shouldn’t be too hard.
Discussion
These devices have no mechanism to push code updates to or hope users will pull appropriate updates in time? Or is your worry just simply too many apps to update, not enough devs?
Most of the devices I worry about dont have a clear path to updating given that it’s a hardware limitation and many of them are more or less permanently deployed. Every esp32 device, for example, will be affected.
