Changes in Searching with Google

Chance Townsend's article discusses how the familiar Google search box and result list has been replaced with spoken or typed paragraph search and AI generated answers with minimal or non-existent sourcing. By neither showing (nor compensating) the source(s) of the AI generated response, users shall have difficulty assessing the accuracy of information, and the work of authors and publishers shall not receive any credit for their work.

Weaponized Incompetence

Callie Ahlgrim explains the term " weaponized incompetence ", which describes a technique where a person declines to accept shared responsibilities.

This term is usually used to describe manipulative stubborness. However, sometimes this behavior can be fostered by a very "competent" person who sharply criticizes every effort of the "incompetent" individual. The result is that the "competent" person is percieved as domineering, and the passive "incompetent" gives up trying. Ahlgrim suggests communication and training tips that can motivate and emable willing individuals to fulfill mutually agreed responsibilities.
