What is a "non-technical" person? If you mean someone who literally doesn't code I would submit that the majority of the articles are not about programming.
More seriously: There are a lot of people with no primary interest in science or technology. They might be really into art, music, sports, politics, entertainment, and probably a million other topics I can't think of that may intersect with technology but isn't about the technology.
That's also a possible answer to the question. There is likely an intersection with technology regardless of your interests, and some people might come here to learn more from the technical folks. Some might even contribute back from a nontechnical perspective.
The more I thought about it, the more I realized that all of the arts involve learning a good deal of technical craft. In fact, obsessing over tools (whether you have the best trumpet, paint brushes, videocamera, etc.) is a special kind of bikeshedding, rampant in art forums.
Musicians and non-musicians?
Ballerinas and non-ballerinas?
Of course there are. Yes where you draw the line is somewhat arbitrary and will vary from person to person but there is still a distinction to be made. You can be pedantic and say "Well everyone is a ballerina, they just might be a really unskilled one." But someone who is very unskilled really isn't a ballerina.
The equivalent would be "are there programmers and non-programmers"
That is a specific job. "Technical person" is not a specific job.
Not everyone who calls themselves a ballerina or a chef has a job as one.
While 'technical' more generally refers to the techniques and tooling of any trade, craft, or activity (arts included can have technical terminology, etc.) - we understand it here, or so I thought, to mean those concerned with our trade/craft/activity, y'know, computers or the internet, or whatever else non-technical family members describe us as 'doing'.
