Apple is getting into VPN now and if I was to guess they would integrate it with some kind of hardware block in their silicon to make it seamless and transparent. I wonder if Wireguard is at the point where silicon makers can actually consider a hardware block such that the VPN is completely transparent to the cores. Personally I find it better to have individual devices do the VPN than at the central network of my home as I find that these mobile devices are significantly more powerful and efficient to do it.
