There are thermometers being used where temperatures are reported to the company that makes these thermometers. When one knows where those thermometers are, one can identify where people are getting sick. So, one could subtract the expected flu count from a particular location and find the excess sickness. These data have identified where COVID outbreaks are starting - before they actually become hospital cases!! Of course, it could be an outbreak of something else, but the data they are coming up with sure looks like it corresponds to COVID hot spots! https://www.nytimes.com/2020/03/18/health/coronavirus-fever-thermometers.html
odd how a crisis makes people willing to give up basic human rights while applauding gestapo tactics... judging by their joy above, bet they'd love'd to have lived in east berlin...
How do you get enough people to use the tech you like for it to be effective? Answer that and I will explain.
I suspect your comment is based on the idea that an individual could be identified by a corporation. However, there isn't any connection to an individual - just to a thermometer which is purchased without providing identification of the individual. Corporations do the same thing with phones - which probably COULD be traced to individuals thorugh account information. For example, many mapping apps show traffic slowdowns. That information comes from tracking phones.that are not turned off.
This is capitalsim. So, producers use advertising, producing a better product, providing unique services (like showing you a record of your recent temperatures), acquiring shelf space from retail outlets, being available through on-line shopping services, cutting contracts with corporate customers (like hospitals) to gain exposure, etc.
Nah, they can just see what's right in front of them better than you can. You're stuck worrying about hypotheticals and expecting people to value your beliefs over their own lives, needlessly.
