Your arguments are very confusing because of the mix of some, most, and all, and the jumping between them.

> few professionals know what ALL of the tools

> developers use (some or most)

> not all of them know

If you are a professional you need to know your tools, in any discipline. It does not matter what most or not all do. If you do not know your tools, you are not very professional.

This is what argument from existential fear looks like.

No its what basic professionalism looks like. No engineer is going to try and do the job of a PLC by manually switching 100s of electrical connections a second. The PLC is a useful tool. If you work with an engineer that tells you "I dont need to know how the system works, the PLC manages that" , theyre not going to be an engineer for very long.

		Sorry I meant the argument parent was responding to and confused by, not their argument. I realize it was unclear.
