What are the fields where the next big thing is pretty close?

I think it's important to follow the fields that are pretty close to be changed. If we look back than we will see that the change happened in fields where the technology was ready for practical application. I tried to think about it in terms of everyday problems that we are ready to solve. Here is my list: 1. Human Resource management revolution. Blockchain technology could make possible "honest recommendations". Imagine if you could find people based on recommendations (started from high school and common around the world) from other people and all of theme are stored in immutable database. It will remove HR specialists, you just need to look for who recommended your employee, and what is the "status" of recommender. 2. Remote meetings Now we already can work out of the office. But face to face comunication is still the most effective way of communication. Virtual reality will make remote meeting more effective and realistic. 3. Everyday routines automatization Internet of things are already in our lives, and there are already critical mass of apps exist. I think it will boost in next 2 years on how we manage all around us: cars, appliances, gadgets... 4. Delivery services Drones are already tested by amazon. We just need delivery services start using them. 5. Self driving cars Tesla and google cars. It's just a matter of time when it will become popular. And what is your list? It's also interesting to see a list where the "next big thing" already happened for the last 2 years.
