I worked at Cycorp (not directly with Doug very often, but it wasn't a big office) between 2016 and 2020
An anecdote: during our weekly all-hands lunch in the big conference room, he mentioned he was getting a new car (his old one was pretty old, but well-kept) and he asked if anybody could use the old car. One of the staff raised his hand sheepishly and said his daughter was about to start driving. Doug gifted him the car on the spot, without a second thought.
He also loved board games, and was in a D&D group with some others at the company. I was told he only ever played lawful good characters, he didn't know how to do otherwise :)
Happy to answer what questions I can
The socially acceptable thing to do is wait for them to catch up but that gets old.
A article shared on HN recently: https://www.bihealth.org/en/notices/intelligent-brains-take-....
Don't get me wrong other intelligent people are on board with me during these episodes, and they are sometimes able to present their specific concern with the solution and that is valuable. I've been wrong before of course. On the other hand the "think of all the complexities" crowd just spout nuggets of wisdom like that until they are able to comprehend the solution, and that takes about 15 minutes in my experience.
