Librarians in the family so no. They are highly qualified and skilled. IMO it is the same as some conscientious objectors during wars who not only would not fight but would not take non-fighting roles (medic, provisions) because it would mean someone else would have that role taken away and would have to fight instead.
Libraries are the thin end of the wedge. They will be telling us that unskilled people can do the jobs of social workers, teachers, firefighters and nurses. Then we will see how well an unskilled, unqualified person can fill in.
I live in a country where well meaning amateurs try to tackle homelessness and addiction (my field). You should see the mess that is made. Sometimes intuitive solutions to social issues are NOT the answer.
I can't catalogue books so why would I try to reinvent the wheel when librarians have trained to do it. It is insulting to them. Maybe we should, instead, volunteer to run the banks. They are obviously run by morons (unlike the libraries) and a volunteer couldn't fuck up worse than the people who were in charge. I wouldn't want a $million bonus either.
