Pros

Talented and experienced people, fair compensation

Cons

Some but not all leaders don’t value their employees, resources are directed away from critical activities to explore or execute low probability of success alternatives, some of the functions are excessively under resourced causing project delays and/or strain on other functions, push to increase efficiency by using AI is logical but it has to be understood that the need to assess the accuracy and validity of AI outputs can put strain on more senior resources. AI increases efficiency in experienced hands but some less experienced users are passing the requirement to look at the output critically onto people who should just be consumers of the info.
