Talking about the people that worked with your dad on that particular site, i have someone who is currently doing such a work and i told him about airdrops but he told me he would choose doing such a work than to waste his time on mining airdrop.
some of them, it was as a result of what they dont know but am glad you are preparing for the old age not minding your children.
the world has really changed and every man for himself. i hope it changes soon and we start looking after ourselves. not just because of entitlement mentality but because of genuine love.
