Now you're arguing against your own analogy? Hunter was ubiquitous position in human society prior to the domestication of animals. 50% of the workforce in hunter-gather societies. Today, 12 millennia after the domestication of wildlife, that number is down to 9-14% of the global workforce dedicated to the production, distribution, processing, sales of meat (not including cooked food) according to opus.
Considering that only 1% of the US workforce was a software engineer I expect similar workforce optimization to occur in software engineering specializations over the next 12,000 years. /s But seriously, it's never going to zero.
No one said it's going to zero. It doesn't have to go to zero for lives to change. Would you rather be a cowboy or a factory farmer? The latter are some of the least desirable jobs in the entire world. The fact that millions of people still do them isn't the point in your column you think it is.
