Here discussion also includes an addition to the ‘data is‘ debate. Véliz makes the comparison with asbestos:
The surveillance economy is not only bad because it creates and enhances undesirable power asymmetries. It is also dangerous because it trades in a toxic substance. Personal data is the asbestos of the tech society. In many ways, asbestos is a wonderful material. It is a mineral that can be cheaply mined and is unusually durable and fire resistant. Unfortunately, in addition to being very practical, asbestos is also deadly. It causes cancer and other serious lung conditions, and there is no safe threshold for exposure.
Like asbestos, personal data can be mined cheaply. Much of it is the by-product of people interacting with tech. Like asbestos, personal data is useful. It can be sold, exchanged for privileges, and it can help predict the future. And like asbestos, personal data is toxic. It can poison individual lives, institutions, and societies.
