The first can be estimated in various ways (revenue per worker, costs per worker, packages shipped per worker, etc) but the second is not estimable. The example I like to use is the advent of the automobile. I'm sure there were a lot of horse-and-buggy drivers or train operators that were decrying the disastrous unemployment it would cause, but the automobile industry now employs more people than that industry ever did, not to mention the new industries it has enabled such as long-haul trucking, taxis, private postal couriers, ride-sharing, logistics, etc. On top of that the automobile industry enables new productivity gains in hundreds of not-directly-related industries such as sales, food service, plumbing, medicine, and so forth.
The average American owns more than one vehicle. They're an affordable, quick way to do things like work more than a couple miles from your home, haul goods, or take a vacation. If the horse-and-buggy operators had got their way we'd have deprived ourselves of many of the luxuries we enjoy today.
