Most cost centers in the past were decimated in order to make progress: from horse-drawn carriages to cars and trucks, from mining pickaxes to mining machines, from laundry at the river to clothes washing machines, etc. Is engineering a particularly unique endeavor that needs to be saved from automation?
Then there's what engineers actually do: deciding how things should be built.
Neither "needs to be saved from automation", but automating the latter is much harder than automating the former. The two are often conflated.
