As Katarina Janoskova says, "So you read a book. You finished it, liked it, maybe even recommended it to others. It changed your life slightly while you were reading it and for a bit afterwards. And then you moved on with your life." I like that. That says it more succinctly.
Network full builds might be faster, but would incremental builds be? Would developers still be able to use their favourite IDE and OS? Would developers be able to work without waiting in a queue? Would developers be able to work offline?
If you have a massive, monolithic, single-executable-producing codebase that can't be built on a developer machine, then you need network builds. But if you aren't Google, building on laptops gives developers better experience, even if it's slower.
Wow... almost 1,600 pages. What a slog. I guess my question is to the OP: What is your purpose? Fear? Conspiracy? Troll? If you want that route, then include commentary on all the other poisonous things humans consume: Copper, Selenium, Chlorine, Sodium, even Arsenic, and etc. These are all elements or compounds or salts that are needed in the human body for it to live. Flouride is a monatomic anion of fluorine, a salt if you will, no different than Chlorine and Sodium as a salt. The data is incontrovertible that "Flouride" helps the human condition more that it hurts it.
Ok, I just HAVE to comment after that: Take any local bank vs Wells Fargo. Who would YOU choose... (unless you've lived under a rock for the last 20 years)
