It has been said many times before by commenters here on HN, and is worth repeating. Cloud-enabled listening devices already have saturated society and are nearly omnipresent. They have a form factor that fits in your pocket and also includes discrete surveillance-enabling conveniences such as: GPS tracking, always-on microphones, high resolution cameras, target-specific network graph data, and access to very large (and inconvenient to monitor) data storage.

If a person is concerned with the practical security implications of Amazon's Echo or Google's Home, I expect they should be terrified of the potential vectors for misuses that their mobile phone allows.

The future state of government regulation and the ability for those in power to use the digital tracks I've left do concern me, but I've found it very difficult to decide how to combat it without fully disconnecting and moving off-grid. There are ways to mask and obfuscate certain parts of that record, to be sure (Tor, proxies, not using Echo or Home, no connected devices, etc.) but I like the benefits that technology brings to me life and I don't really want to move into a remote, signal-free location to live a spartan life.
