Reaction to "refabricating architecture"

After reading "refabricating architecture" I wonder if the continuous discovery in advanced technology methods of fabricating products worldwide will negatively affect our economy.  Will the "more for less" theory,although smart to a business owner, affect the number of jobs that will be available in the years to come.  New machines and tools which facilitate the production of all products result in lower man hours.  If these machines continue to decrease the manual labor required for production, where will the surplus of people turn to for jobs?  


Economically speaking, it seems to me that the result of the steady technology discoveries will result in an even higher unemployment rate, over the already embarrassing numbers.  And the only solution that seems feasible to me is that an adaptation period has to occur, and that would be regarding the fields of study that our population begins to migrate to.  In order to successfully adapt to the change in technology, students will, in theory, begin to study computer information systems instead of construction work, either on a building site or the production line. The reason for this is for the increase in computer technicians needed to operate the new programming systems.  


Something else that I feel might happen for a period of time before being solved is the flaws of the technology.  It seems that the first few passes at creating technology to replace hand craft (fabrication of products) would fail due to lack of quality and consistency.  Machines tend to fail at consistency and I think that keeping this to a minimum will be the greatest challenge in production for years for come.  This is not a change that can happen over night; it takes many attempts over a period of time to perfect the machine production, especially at the scale of production being attempted in today's warehouses.  The reason I feel that the possible failure of the machines is important to talk about in this blog is because this creates a standstill in our economy if failure does occur.  A standstill amidst a transition as such is detrimental to our society.  


I had an unusual reaction to reading this literature, and instead of a more theoretical approach to architecture, I feel that attention to this situation should be established.   Is the result of continuing this transition to a technology-run economy worth the possible economic tragedy that would result in a failure of this transition?  That's what worries me.
