The surveillance already may be deeper than we think. On Monday I was in a car, four hours from home, with four other people, all with iPhones. We passed a business I’d never heard of, and I mentioned I’d like to know more about it. No more was said about it. Yesterday, on our way home, I checked my email and had received an email from that very business, a chatty introduction to their products and a link to their blog. Other than sidebar ads generated by my actual browsing, I’d never experienced this, and thought I never would because we don’t do Siri, Alexa and such. But it seems something is listening to speech anyway.
