Author here, I appreciate the feedback but I feel like there's a falacy here. If we asked respondents if they liked ice cream, and it turned out 95% of survey respondents hate it, would you say the rest of the data is not valid because the survey is clearly not representative of the general population?

The fact that the survey may not be representative on things like immigration or its Japanese audience has no relation to the data's validity on completely unrelated questions such as developer's outlook on AI.
