>rushes to defend the tool's use is because holding humans accountable would mean throwing these tools out entirely in most cases, due to internal human biases and a decline in basic critical and cognitive thinking skill

The magical past where people had critical thinking skills never existed. We put a lot of trust in tools is because people are unfucking reliable. Hence why in most cases actual physical evidence does a far better job than witness testimony.

This said, people are lazy. It is one of our greatest and worst traits. When we are allowed to be lazy, especially with tools bad things happen.
