The reduction of manpower in agriculture has been going on since the industrial revolution and has been key to our prosperity. If you think being able to eat until you are full and have the energy to do other productive things then be glad that this trend continues.
A big negative is most workers have been forced from God's country into the city communes where they learn to vote communist. Politics is driven by population density: the more tightly people are packed in the more rules and higher taxes are required, and the less freedoms are allowed. Hopefully self-piloting cars and aircraft and high speed internet will reverse some of that trend.
