That would be reason enough to invest at the ground floor: virtue is its own reward. But you're also building social capital with a person who might actually reciprocate. Replying to every one of Elon Musk or Lady Gaga's tweets is evolutionary wasted effort. We were wired up to simp for powerful or attractive members of our tribe; not for a senpai who we will never meet and doesn't know we exist. But if you invest in people who are not yet famous, or are 'famous' in some very small niche, you might actually be able to befriend them, or otherwise earn their favour.
