Ask HN: Who is the most positive impactful person you know?

It's a fine answer. He spends his time railing against Marxism, Postmodernism, SJW culture and telling people to take responsibility. His main messages seem to boil down to become resilient and don't destroy the world.

It won't be anyone that uses the word 'impactful'.

Mr Musk's company SpaceX has brought down the cost to orbit by a factor of three. That's a big deal. Not as big as Edward Jenner & Louis Pasteur (vaccines) or Isaac Newton, but still pretty big.

I'm going to change it a little to the people I've met that have had a sizable impact on the world.

I've met Sam Altman briefly last year. His involvement with YC the past several years and co-founding OpenAI have directly and indirectly touched thousands of jobs.

I've also met Michael Seibel. His involvement with YC the past several years has directly and indirectly touched thousands of jobs. His co-founding of Junstin.tv allowed it to exist, it is now evolved into twitch.tv which has allowed some creators and gamers to actually earn a living streaming and has created tons of micro-communities for video games and table top fans to both play and watch.

Aside from them, I don't really know (nor have I met) anyone else that I feel has directly and indirectly had as much of an impact on society as those two although...

I have very casually known, but never met, Kate Bornstein since our mutual participation in the Save Caprica campaign. She's certainly been a bastion of hope for many LGBT persons. She's semi-active on various social media. https://en.wikipedia.org/wiki/Kate_Bornstein
