Have you chance to elaborate why this guy deserved this? Did he build first neural network, lisp machine, ALICE chatbot, break image net. I always considered him as some kind of celebrity from science, while other guys, which names nobody remembers, actually pushed AI movement by doing real things, while working on Google Brain, Watson, cyc, trying to catch spam, terrorists and fraudsters.
Seems like the admins have pretty much done away with the black bar thing.
You won't see the top menu links.
When I see a black bar on Hacker News, it serves as an alert to me to scan the news more carefully. Although I knew who McCarthy was, Jobs, etc, I didn't know this person. The black bar alerted me that someone in this community that is considered quite an influence died. Now I'm reading all about the person in various articles. The black bar helped to alert me to that.
It'll be fun.
