Misleading
> Among the 270 jobs in the 1950 U.S. census, only one job was automated away — elevator operator. But many others were rendered obsolete by new technology, like the job of telegraph operator.
In that same time farm jobs went from 15% of the workforce to 2%.
Farm employment itself has decreased 4x compared to 1950 (the % figure overstates it since the total workforce is larger). However if we consider the broader "food" industry employment has increased substantially.
Thus we may see "coder" employment decrease but the broader "software/tech" industry increase in employment.
