I tried creating a question asking what work is involved in creating a facial recognition app and got recommendations on my life and how to spend my free time...
I want to talk about what kind of libraries are available to do a certain thing within Android and what kind of difficulty a task is and I get mundane irrelevant answers ending in my thread being closed?
I guess here's another Exchange group that should be forgotten. Out of 5 answers, not a single one was relevant to my question.
Q & A, of the type that we practice here at Stack Exchange, rests on a few fundamental principles and assumptions:
There are very good reasons why we follow these principles. If you've ever tried to get an answer to one of your questions in a forum environment, you already know why we have these conditions: it's very nearly impossible to get a decent answer on a forum. In short, forums suck.
So we do everything we can to avoid those forum behaviors that prevent people from getting good answers to their questions. This reduces the noise and is more attractive to those subject matter experts who are here to provide answers to your specific questions.
If you are not aware of these principles, or fail to follow them for whatever reason, you're going to have a very hard time participating anywhere on Stack Exchange.
What you were asking for is a topic where a useful answer could fill a whole book. Such questions are usually considered as too broad for the Q&A format of this site. Note that facial recognition is still a topic of scientific research.
You argued it is not too broad, since you only want to know how much work is involved. However, that is nothing strangers on the internet can tell you, because we do not know you, your background, what exactly the features are you imagine for your program, or the quality of the facial regcognition you expect. Each of these details can easily make a difference factor of 20 or more in the resulting effort. So even if your question would not have been closed as "too broad", it should have been closed as "primarily opionated".
Moreover, it is not "illegal" to talk about technology here. Almost any question on this site has a specific technological context. However, we do not give any technology or library or tool recommendations, and questions asking for such a recommendation are typically closed quickly by the community, too.
