Tiny bubbles, of the mind (make us feel happy / make us feel fine): the way technological mathematics limits our thinking, enclosing us in ever-smaller circles of awareness. From the article:

The ubiquity of incredibly powerful algorithms designed to reinforce our interests also ensures that we see little of what’s new, different and unfamiliar. The very things that are at the heart of learning, understanding and innovation. Rather than taking us out of our comfort zone, the digital revolution is enabling each of us to live happily in our own worlds, and in the process closing down opportunities for originality, spontaneity and learning.

The best part of all: we love it this way.
