Yeah, he presumably put away a nice nest egg working at Google. It's not in any way wrong to remind others that, if they're lucky enough to be in a similar position, they don't necessarily need to work until "normal" retirement time if they/their families don't want that.

Personally, I feel like I got a bit greedy and could probably have called it quits a year or three back and been happier for it. I partly blame COVID for disrupting what might have otherwise been a better transition.
