I was reading through the govt blurb re the app to help people eat/live more healthily. On the face of it, a good idea, seems to offer carrots and no sticks. I only baulked at the phrase our world-leading healthy weight strategy.
I do wonder how the app would know how many fruit/veg you were eating, does it rely on one's honesty? I do think it would need to be tweaked a lot to allow for people with disabilities and health issues, otherwise they could not take part, but that could be addressed.
However...and I can't recall the country this goes on, maybe S.Korea, or Singapore? Where you get reward points for being a good citizen and lose points or get excluded from things if you make undesirable choices, tracked by phone apps. Was on the BBC a few weeks ago.
So to the people who ask what's wrong with an app to encourage people to live more healthily - well, nothing. It's the potential expansion of that trend, with more data tracking, rewards and then the introduction of penalties (you put on 2 lbs this week, you're shut out of buying any sweet food items for a week as a result, as a trivial example). All this can be monitored by your smartphone and geolocation data, all shops are linked to a database where everyone's points are tallied and behaviours followed. Add in to that one's health records - and yes, potentially mandatory vaccinations and other health checks. This is what some of us fear could happen at some point in the future, and I don't think it's a stretch to imagine it happening. It all starts with good intentions, but with different governments and people in power, that can quickly change. There's plenty of science fiction along those lines, but it feels less and less like fiction these days. Don't be too sure it could never happen. It already is in some places.
