What do you mean? He was funded by SRI for a long time, and spent time visiting other people and spreading the word. I first met him when he visited PARC, probably for the upteent time but I’d just joined.
He was full of interesting ideas, not someone who just had one big insight long ago, and was great to talk to about your own work.
His memorial service was full of amazing people whom he’d met and worked with in the Valley over the decades. Mind boggling how that works — quite different from a fully remote world. We talk about WFH vs office, but less about the value of running into Doug engelbart or don knuth while walking down the street.
