Those pictures make me nostalgic for the 1998-2008 era. Back when 99% of people didn't have a camera in their pocket. Having a camera/camcorder at a convention or event like this was so much different.
Not only that - Linux fanatics looking geeky, long hair, penguins. Now they look normal, where AWS t-shirts and get enough TC to retire at 30 having helped Bezos get more power.
