For those in the thread worrying that KK may have been mooching off people, and would not reciprocate: many years ago, I opened up our back yard for people who wanted to come to O'Reilly's Emerging Tech conference, but could not afford the sky-high hotel prices in Silicon Valley (this was before AirBnB or couchsurfing).
I was surprised when Kevin Kelly appeared. He'd been my (very distant) boss at Wired, was a published author of one of my favorite books, a very well-known figure and a smiling but disarmingly calm manner. He sat and amicably talked for hours with a yard full of people, many of whom have become some of my closet friends. Then, as the evening closed, he asked if he could sleep in my yard too. Others had brought tents, and burning men structures, and it had begun to rain. Kevin pulled out a camping sleeping bag from nowhere, struck out, and I saw him later, in the soaking, muddy garden, quietly curled up under someone's geodesic dome structure.
Decades later, after Covid, I mailed him out of the blue, and asked him for advice. He immediately remembered me, invited me to his home, and talked to me, again, for an hour or so, about AI, optimism, and how to change the world.
To be frank, I never emailed him thank you, and I still feel guilty about that, but now I feel like it was never needed or asked for. I may mail him anyway. Maybe there's a miracle or two still left in the day.
