There's this attitude that because computer work on pure logic, anything a computer does must therefore be logical and rational. The problem is that the humans who program the computers will often encode their own illogical, irrational, biased, and flawed logic. The computer is not logical and rational, it just follows instructions well. If the instructions are illogical, irrational, biased, and flawed---but executable---the computer will follow them. And when they spit out a illogical, irrational, biased, and flawed result... well, it must be logical, rational, unbiased, and unflawed, because the computer is purely logical, rational, unbiased, and unflawed.

We code our biases into the algorithms we use every day. They inherit our flaws. The sooner we all wake up to this, the better.
