I have finally come to a conclusion that Chess is a total waste of time for people who don't take it as a career/profession. For people (players, coaches, Arbiter etc) who choose the game as a career, spending time on openings, Gambits, endgame does not seem to be a waste of time. For them chess joins the category of all professions from Wall Street to Hollywood . But for others, I don't think chess is a useful hobby/pass time.
The problem simply is that Chess takes too much time.
If you are an adult, playing Tennis twice a week for 90 minutes each time and therefore a total of 3 hours, is generally more than enough. Some play two hours or even just one.
Chess on the other hand... unless you are just playing a couple of games almost as a goof at some family barbecue every two months, is a very different story.
It takes a lot of commitment, a lot of time, with all the studying and such.
How many, among people who say 'they play chess', spend only two hours per week on it?! Realistically.
Golf or most videogames are the same story tbh.
