To be fair, I haven’t seen much concern expressed on the theme of this tweet,
Has anyone considered that Facebook's “How Hard Did Aging Hit You” Challenge is just a way to refine facial recognition technology? What better way to get people to offer up a ton of comparative visual data?— Greg Britton (@gmbritton) January 13, 2019
but with over 5 000 retweets (at time of writing), it certainly seems like some people are convinced, and possibly concerned. I’m however not inclined to think that the “10 year challenge” is a sinister ploy by Facebook to harvest this freely-volunteered data, in order to improve its facial recognition technology.
