IMO, butlerian campaign requires a combo of good robotics affordability, decent wages and rising demografic(US popn is till rising). Just like for the next few years or so, considering these cost factors, there's still much more room for low-valued added manufacture in vietnam and hindustan while china has become the biggest market for robots. Save oil arabs, the combo of large popn,poverty,low affordability will delay robotization in ummah countries. It's a matter of production cost and employment/demografic issue.Of course sooner or later, robots will take over manufacture

2nd butlerian jihad/crusade will happen when human males and females prefer sex with androids to sex with  'biologicals' and  embryo reproduction become a technical process.

BTW,a few days ago I was told by a Bank of china 'investment' person that many  HK chinese investors want to move low value added manufacture from china to vietnam and hindustan, He said cost/labour in hindustan is only one 8th that of china. I'm not surprised if that's only one 5th(becos china ML GDP is 5 times that of the hindus while popn is only 2 % hier); but one 8th? I guess because of the deomografic dividents, wages&benefits  are suppressed in bharat. I read many factories in guangdong province provide lodging for migrant workers. I also doubt if the present gen of chinese youngsters aspire to be cheap factory labours. If chinese popn could drop fast, there'll be great demand for old age nursing robots.
