My 5 Cents
I find I am becoming seriously annoyed by what futurists think and say about the future. Even the idea of "most popular jobs" is a strange one. Most of the items listed are natural branches of already existing professions. Body part maker and the other medical jobs would naturally be performed by doctors specializing in those particular areas. We have always experimented with genetics in livesock. We get a known good breeder female and a known good producer male. The climate change specialist and weather modification police is another irritation. Man is too finite and the planet is too big. Even if we could, human nature is to think too simplisticly and mess things up.
Elderly wellness consultant? Right. How will wiping drool (and worse) become popular, exactly?
As far as verticle farming, we in America have LOTS of space yet. As for the global food market, the causes of starvation in 'developing' countries is political, not 'technical' or environmental. Veritcal farming is a neat idea, but it will become a reality IF it is practical and cost effective to do so.
I guess I am most irked about 'most popular' idea. That turns the technology gains of the future on its head. Useless waste of time.
