Currently industrial machines on a non pvp intended landscape have an infinite lifespan.
This means that the market for them is only as viable as peoples lack of ownership in them and nothing else, once u get one u have it forever and that... that is unsustainably broken.
Id think that a 6-10 week operational lifespan, with machines throwing random errors after thier lifespan stopping production, and requiring either consistent repair or just flat out replacement.
This will create a sustainable market for industrial machines ... i think.
