Well that is understandable since most people are, at best, amateurs outside of their field of expertise, and sometimes within too.

But thankfully not everyone's opinion is of equal competence nor should they be treated as if they were of equal competence. And we don't have to spend much time worrying about these folks.

For example, if thousands in positions of importance started advocating to replace the publishing industry that would be worrying.

But I highly doubt several thousand disgruntled junior folks could destroy the publishing industry, even if they combined their efforts and committed their all to it. And I would bet very few of these folks would ever climb into positions of real importance so they aren't much of a latent threat either.
