What might humanity do in 30 years?

At the start of the 20th Century, the majority of Americans were farmers, today that number is less than 2%.We've created new jobs. Most jobs that exist today didn't exist 100 years ago. In fact, in 1910 service jobs and agriculture together accounted for 70% of the US labor market. Today, service jobs account for almost 80% of jobs with industry making up the remaining 20%. In the past 10 years alone, we've seen the advent of new jobs which are now widespread, including app developer, social media manager, cloud computing specialist, data scientist, sustainability manager and YouTube content creator, amongst a plethora of other roles.
