Thanks for great explanation! people should no longer think IBS is low tech. In fact I think IBS would eventually meets 3D printing if not already.
A bread factory churning out tens of thousands of loaves of bread daily using high tech methods and fully automatic equipment coupled with distribution network to send fresh bread within hours to various destinations near and far.
A neighbourhood bakery churning out a few hundred loves of bread made by hand and only retails to the neighbourhood.
You may say the first is high tech and the second one low tech.
But actually they are both belong to the low tech industry.
