Many years ago, manufacturers realized it was cheaper and more efficient to have robotic arms process the materials in the assembly line, however there was a flaw coming that few foresaw... We tried to tell them, computers would never replace humans because artificial intelligence lacks the reasoning element, and it can not predict humanly foreseeable consequences. But, they wouldn't listen. Unlike last century when humans would assemble the machines, today most assembly lines are operated by robotic arms that complete the machine assembly process. When the process first started, humans were used to 'train' these robots in the fine tuning process, and all went well... But that was only so because the humans who did the fine tuning had just recently been a physical part of the assembly process themselves, they were in fact, past assembly line workers... They knew what they were doing, they knew the intricacies and flaws of the machines and thus fine tuned the robots to adjust to the imperfections themselves. Today, few humans exist who have physically assembled a machine. And the tune has been lost, the experience that is used when something won't fit quite right no longer exists... I know, I've worked on an assembly line, physically putting machines together... Trust me, it's almost never 100% according to plan, no two machines are even exactly alike, yet the robots assemble as if they were. Today we fine tune the robots from notes left by our ancestors, mere numbers that spell out specifications, year after year... Little imperfections have crept in, at first nobody noticed but now there exist no work-arounds. Today every year the machines are looser, more and more mechanical imperfections keep creeping in. Because nobody is at the helm anymore. When automatic pilots drive the ship, sooner or later it hits an iceberg it could not see.
