Are lay articles good enough to be the main source of information for PhD research? Doing PhD in new field that does not have enough resources in it. Most of the information I find are articles written in websites such as medium.com. 
I really feel awkward citing a website article, as I feel it is not good enough. It is not from university, it has just the author name, not much info about him/her, and the way it is written is for non-academic purpose. 

Is it ok to have many of these articles as the source of my information in my PhD? If it is not ok, then what can I do? there is no reliable resources! The field is Artificial Intelligence.

To be more specific: It is not about AI in general, it is about a topic in AI that has not been explored thoroughly, the only place that has done that is Google and they keep the research they have done private and not accessible for public, i have contacted them but they rejected to help with their research

Edit : I know that there are millions of AI researches in the internet. but there isn't anything I was able to find on the area i am studying. google has a product and they are selling as a service and they are not publishing the research they have done on that area, i have contacted google and they did not allow me to look at their research.. there are other researches on other areas may touch that field but none i found on that field specifically.
I find the entire premise of the question quite odd. First of all, to answer your question: I’d say that in most cases I’ve encountered the answer would be no, you can’t use popular science articles as a primary source. 

That said, I seriously doubt that they’re all that’s out there. Google works on this problem: they came up with it and no one else ever heard of it or studied it? How did the popular media hear about this amazing idea that has somehow eluded the entire AI research community except Google and your advisor? I feel like you’re either looking at the wrong sources, your advisor is not pointing you in the right direction, or something else is off.
