There are certain subjects that every generation discusses and with good reason. What is the meaning of life? What is love? You grow by discussing them and coming up with your own answers. I found what I needed in my answer. There is no right or wrong answer to these questions. Discuss away. I am interested in your answers. I also understand that until you have answered these questions for yourself mine must seem suspect. Older generations, younger generations. We have more in common then you'd think. It seems when your young (and I don't have any idea how old you are) you feel that you are the first to think of these things. I know we were sure our parents never had deep thoughts, had wild sex or did anything like we did. Now at 56 I realize they did and think it's funny when I read an article about how our children think they have discovered something new. Technology has changed but not philosophy.
The problem here is your fundamental premise: “there is no right or wrong answer”.
Clearly your premise is wrong, and in fact there is a “right or wrong answer”; that is why the questions are being asked, and why these kind of discussions persist.
Regarding the other points you raise: all are valid observations, and presumably will be addressed by the people doing the research. It will be interesting to see what they come up with, assuming they publish.
