Big data algorithm recommendation is like a double-edged sword, it conveniently pushes the content I am interested in, but it also makes me gradually fall into the comfort zone of information. Gradually, I found that I was exposed to more and more information

Big data algorithm recommendation is like a double-edged sword, it conveniently pushes the content I am interested in, but it also makes me gradually fall into the comfort zone of information. Gradually, I found that the information I was exposed to became more and more monolithic, as if I was being cut off by an invisible barrier. This information asymmetry unnerved me, and I began to wonder if my vision had become narrow.
