What type of achievements, credentials etc. is required to define someone as an expert in a field of study?
Do you need to be a researcher of said field and have published papers, and journal articles? Or have written sections of whole books on subjects? Etc.
What are your opinions on this...
My job isn't in the list but it is VERY likely it'll be taken over by robotic automation in the future. Machinery operator in a freezer storage for a large grocery, this can easily be reduced to automation. Luckily this is my part-time job throughout uni. :D
