I know what an OS is but I won't say how and that isn't the issue here.
The question is why are you avoiding answering me what knowledge have your gained in your "40 years of great grand experience with OSes" ? Can you in an hour contact two people in India and form a team to start developing a reliable, responsive, GUI OS like QNX Neutrino but even simpler than it ? Can you in one hour get those two people to agree to form a company in India to develop this OS commercially ? Just drop whatever job you and those two are doing and set up a company for this.
