After you make first few and insert them into assembler thats making them you can start mass manufacturing them easily.
And putting them in other things makes things a bit weird - especially with the speed bonus of 4-5 god modules (only using grade 1 for now). It looks like I could de-construct half or more of my factory and produce more. Only limiting factor is speed of inserters.
Not sure if thats related but game started lagging for me after I started switching to god modules.. not sure if it's related
