I've been reading Ten Reasons to Delete Your Social Media Accounts. Much of it is stuff you already knew (albeit well-organized in this book) like the problem of social media intentionally destroying shared reality and the provoking of negative emotions to increase engagement (or as the author calls it, behavioral modification).
There's been several surprises, though, like the fact that the all-encompassingness of social media has people thinking there's just no other way. He compares this to what people think about Uber: That to have a convenient cab system, you have to exploit drivers and have a nice app for coordinating them. Most people have gotten to think that it's impossible to both pay drivers reasonable and to have a nice app.
Similarly, the inevitability of no-charge ad-driven software is rarely challenged in social media.
The other unchallenged assumption the book mentions is that people do not deserve to be paid for the data they provide which makes machine learning models that generate millions of dollars. Machine learning translation, for example, is said to be making human translators obsolete for many use care. But who provided the data to train those models?
It is wrong for a corporation to seize knowledge from people in order to (literally) enrich themselves.
I have thought before about Gmail, Twitter, et al taking their users' data in order to build models that make it easy for their customers to modify their behavior, be the customers shoe sellers or intelligence agencies. But certainly, they also use this data to train models that will make whole industries obsolete and put these users out of work.
