That's an unrealistic view. It's unlikely. Firstly because we already have well defined systems for that which are tested in the field and are specifically designed for it and emergency routing (InReach for example). Secondly a lot of places people tend to go backpacking have limited search and rescue capabilities so you're not guaranteed a rescue anyway. Thirdly a lot of places it'll get stolen before it gets used.

It's a toy and another damn thing to carry around and a load of marketing around it to sell it as a suitable replacement for proper kit.
