Your reasoning could be applied word by word to the latest novel by Stephen King. I may know that it has been written by an army of mercenary ghost writers and nonetheless enjoy it and warmly recommend it to all my friends. Judge a book by its content, not by its author. Do the same for software.
So you enjoyed a book written as a collaborative process between multiple human writers and somehow this is an argument to have less humans involved...?
I would rather frame it as an argument against credentialism.
