So here's a thought exercise. One cannot predict the future well, but for those who are inclined to try, there are the ones taking faithful fliers, and the ones trying to get the answer right. Still, what is a safe bet? 

Anything that improves the quality of life, and can't be messed up by the government, (stupid supreme court,) is on the table, and anything that is happening now and has room for improvement is a fair bet. 

In Sweet, when dividing broad traits to four spacefaring nations, I'm not remotely trying to be predictive. Venusians are too much genetic engineers, Pacificans are too much androids, Mediterraneans are too much Cyborgs. They probably wouldn't be divided so starkly in reality, but it makes the story flow. Jovians are too much in tune with their wetsuits. 

This is existing and emerging tech. Here is a sciencedaily article and here is raman spectroscopy, a breakthrough discovery that's going to take it to the next level. If you want to start a business, get in on this racket. 

In Sweet I avoid sticking my neck out too much. Some for fun, but I mostly am only using real world tech, for example the above. Stuff that exists but hasn't been made ubiquitous yet. 

By doing it that way, I am laying out before the reader, options. Tech isn't an obstacle to overcome. How do you get to there, from where and when you are now?
