[Overwatch] How many lines of code would it take to program an Omnic? do the Omnics program other Omnics? Is the technology used to create Omnics available to the general population?

Omnics can only be created by an Omnium:  an automated, self-improving factory which gained sentience (kinda like Skynet).  There were only 3: 

- Australia: destroyed, which created "Mad Mad" land.

- Detroit: currently deactivated

- Russia: under omnic control, causes 2nd Omnic Crisis

And while an omnic could probably make some changes to the code within the Omnium, the amount of code required is far greater than any single omnic can write. If at all, since the Shambala think omnics aren't coded, they're imbued with a soul.
