I'm the "12 years at Google" commenter from below.
Got a personal email from Craig Silverstein my first day at Google welcoming me to the company and thanking me for my work on hash functions. Chatted with him occasionally after that. Good guy.
Reminds me of a funny story - the first day at Google (2018) I got a chat from an SVP, I forgot who, saying "Hi!". At first I was blown, wow, what a company! SVPs greeting new engineers! A minute later they were like "oops, my bad, wrong person".
They intended to message someone else with my first name, so my guess is they used to type that name and hit tab to start the chat, and that person was no longer the first option in the auto-complete since I joined.
(side note - the most bad-ass response to this would have been to just send back "go/no-hello" ;) )
But all hope is not lost yet -- even though the work environment might change from big family to big company to big factory as the company size grows, it has gotten to the size where there are now pockets of families that are cohesive among themselves. I believe these fractals of families will be what carries the culture forward.
