My phone is not a home. It’s a filament in a fabric of affordances. I rely on others to support those affordances. I pay for some of them with money. I don’t want a castle. I want a society.
Your phone contains records of all the actions you take with those affordances. What you are looking at, who you are talking to, messages you've sent, inside and outside apps, plus a time series of sensor data that position you and can give audio/video of you at all times...it is foolish not to treat access to this device with great care.
Your phone is a little portable wannabe Orwell's telescreen, with more sensors than even Orwell could have imagined.
