"not ... smart", "[only use is to] win stupid games.", "[you will spend] your life doing jobs you hate for money".
My dude, I'm learning Japanese vocabulary, which has helped me to start reading light novels for fun. By your argument: I'm not smart, wasting my time, and hate my life, or soon will?
Thing is I would fully agree with you that memorizing != comprehension, but that doesn't mean than memorizing is without it's use. Do yourself a favor and learn to not be so rude. It is literally the first item in the site guidelines:
> Be kind. Don't be snarky.
You also said reading stuff in English give you less satisfaction than reading in Japanese.
You might want to reflect on why that is the case.
