Alan Kay responded above so...
I'm a little skeptical. That user certainly writes in a similar style to how I've seen Alan Kay write online, but I wouldn't be opposed to seeing some more proof. A one-day-old HN account claiming to belong to one of the most important people in CS from the past 50 years seems a little suspicious haha.
Also, I walk by your face a few times a week whenever I head into my lab. MEB has redecorated a few times over the years, but they always have a section of pictures of notable alumni and (of course) you're up there. Thanks for giving us a good name in the field and for all you've done!
