Answer 1

Using the word “professionals” to refer to the people and their work in that field is dangerous because it tends to conflate the well developed skills and techniques in other fields such as construction (aka engineering) wherein the professionals can use the techniques of their real science to actually make something specific happen that contributes to others.
