To be honest, the sample of the Guardian's study is also quite light (a dozen people) and with much more selection bias (people who work with AI).
As is the sample in this article. You will surely find as many physicists saying earth is flat, mathematicians who hold that Cantor was wrong, and medical doctors that tell you vaccination against measles is overall worse than not.
So? People sharing their experiences is good. Not everything is a scientific study.
True and opinions are often discarded as irrelevant in internet discussions in favor of large-scale studies.
