I wonder what the difference is between a CTO's relationship with the company they are building the tech for, and a civil engineer/architect/foreman's relationship with the company they are constructing a building for... Maybe the CTO never stops building? Is that enough of a difference for why the average CTO has stock options and (I presume) the architect/civil engineer/foreman etc doesn't have stock in the company that hired them? Both involve organizing massive amounts of human labour and resources over years and building something the company is dependant upon to succeed and function.
