I hope you are not struggling with depression. And if you are, please seek professional help. Random people online won't be able to properly help you.

In terms of avoiding mass surveillance, it's sad but we have to accept it will always be there. People with power will abuse their power. It's always been like that, it will always be like that.

Battery technology isn't good enough to power smartphones to be constantly transmitting everything they capture from their microphones to the cloud, or even less to run a constant speech recognition model that can also identify who's talking.

Worry about what's on your devices, your network, what you do with them, and about what tools you use to communicate with others.
