Here is a pretty typical framework for tech innovation. I will use cars as an example.
1) New Tech appears. Disruption happens. More jobs, but people realize old jobs will go away.
Cars invented. Lots of new employees hired to build cars. Everyone involved in the horse based transportation system feels a chill.
2) More people being hired, but old jobs start vanishing. Still more jobs than before, but everyone can see the writing on the wall. Multiple car companies appear. horse trainers, raisers, carriage makers, all begin to lose business. Some go into the new business, others are in trouble.
3) Old business vanishes. New business is so much cheaper that poor people start using the new business, something they could not afford to do. Things that were rare become common and new related businesses start to rise. Less than 1% of people still using horses. But workers at car factories can afford a car, people start bussing kids to schools, and gasoline stations start appearing. Surprising, STILL more jobs than before. Why? Gasoline is a huge business. Where there was one horse per rich family on the block, two car families are common.
4) Even more uses/ businesses start to appear. New problems are created AND solved. Car racing is easier than horse racing. Government need to police the car owners, regulate the businesses and the vehicles themselves. Cars need new tricks - including air conditioners, towing capabilities. RVs appear. Car Insurance appears. Refrigeration trucks appear. People use cars for minor trips to the neighbor 20 blocks away (god, the kids are lazy....). The total number of jobs has actually risen far beyond what the horse based transportation system allowed.
5) New tech totally disrupts the old one - go back to step 1. Electric cars and self driving cars.
