Strongly seconding this (especially as someone who was backstage with Jeff and Tony right before that demo). What's less visible is the impact and influence Jeff has had in enabling leaders and founders to do the right thing. So much of the pressure and industry influence on CEOs is to be short-term thinkers, to ruin their user experience, or to be harmful to workers.

I've seen, both personally and through others who've relied on his example or mentorship, Jeff be a force for good for those who were trying to do right while leading companies. And to even be someone to call in (or call out) a mistake when you make it — which a lot of bigger-name people are way too cowardly to do. He's also spoken up for his city, and for vulnerable communities, when it would have been so easy for someone of his stature to just stay silent.

It's obvious that Jeff is a brilliant technical innovator, but he is just as much of a pioneer of thoughtful and conscientious leadership in an industry that's become woefully bereft of it.
