Maybe if there was a mainstream reason to connect home machines with their phones. Personal backup, game streaming, etc. im not in this camp of believing it but maybe!
I do this - I self host my movies/TV, ebooks, comics, photos, etc. and use tailscale to access it from anywhere. It's not really great for "mainstream" but for "tech enthusiast" it's very useful. Basically anyone who would consider buying a NAS (most consumer NAS devices can also run Docker containers these days)
