My current approach is :
A used linux flashed thinkpad laptop and pixel phone
Thinkpad on isolated network
Thinkpad runs mullvad vpn
Clawbot on thinkpad
Clawbot uses my own Routstr node for private AI
Only add what you want bot to access to thinkpad
Gives you screen, keys and microphone on device
Pixel runs graphene
No esim wifi only
Marmot chat with clawbot for remote interface
