Answer 2

It's possible but complex and it is very unlikely your OS will be able to compete with google, bing, Linux, Apple or any other OS from a major company. Also *operating.
And If you want to do it I would recommend learning about cyber security because a lot of Operating Systems have back doors and all kinds of security errors. You will also have to have a vast knowledge of hardware and software. Those are factors you should consider if you are serious about this.
