SO if it benefits only group it's not good enough for you, pro? I have free math education for those who can't afford proffesors. I solve all tasks they have for entrance exam and share it with explanations. And beside that I have education youtube channel and as well website. Good enough from me , atm.
Ohh, you do research. So OP. So benefitial for humans. Until you DO something, it's useless .
