People in the plant design business have been suffering from offshoring and increasingly-automated data-centric design software.
Expensive,
sophisticated,
software run over the internet by people earning 1/10 to 1/3 "western" hourly rates means that as older, more experienced workers retire, they are not replaced (or at least not on a 1:1 basis).
Most of the problems with offshoring are miscommunication, time zones and cultural.
Tasks that were formerly performed by younger people entering the field are now done by the software (eg., cable routing, single-line diagrams). Offshoring and automation are great for cost reduction but this does not bode well for people looking to enter the discipline.
