Many captains of technology are openly predicting the demise of humankind from advancements in automation and artificial intelligence (AI). The Luddites — 19th-century textile workers who believed weaving machinery threatened their jobs — said much the same thing, sans AI.
We must recall that mankind has created, endured and grown from nearly every technological advancement. The Luddites did not get their mill jobs back, but their descendants are doing quite well and wearing much less expensive clothing made from machines. My semiconductor industry all but did away with vacuum tubes, which would not be suitable for the smartphone in your jacket pocket. Milking machines did replace milkmaids, but I am hard-pressed to find a modern woman who wants that job.
Why, then, do tech titans loathe automation and AI? For the same reasons the Luddites feared weaving machinery.
