3D printing. The rapid printing of three-dimensional objects allows inventors without a lot of resources such as a machine shop to prototype their inventions. 3D printing also allows small businesses to create products and works of art that can compete with large businesses in terms of quality in design. Even without 3D models a business can still sell its products by selling the files for making the 3D items on-line so other people can print the items on their own 3D printer.

Many items can now be 3D printed from plastic, metal and even food can now be 3D printed. Hospitals are currently using 3D printing technology in such applications as prosthetics.

When it comes to 3D printing development what I am really excited about is working toward a 3D printer that can print other 3D printers. RepRap comes close because it can print most of it's own components. Once a 3D printer can fully print another 3D printer it would enable a lot of poor to be able to have access to cheaper products by owning their own 3D printer.

The Blockchain Technology specifically STEEM!

Yeah I am a believer of what STEEM can do in the years to come. And since it is now starting to gain attention and momentum from the outside world it is not at all impossible that in 2020 it will revolutionize the world, just like how the creation and release of the world wide web to the general public did to the world years ago.

I mean common, getting some extra money just by commenting, liking and even viewing contents? There's even an app now that rewards people for just burning calories and/or walking and running and a platform to review where you eat Basically almost every fun activity one could do will now have a potential to be rewarded. In 2020, People will now have a new motto and slogan: "Lazy-with-a-purpose"

Clearly artificial intelligence will upset the world through its applications in different areas:

Autonomous Vehicles: Ford recently announced that they will have a 100% autonomous vehicle on the market by 2020.
Robotics: More and more jobs are at risk of being removed and replaced by robots such as front desk and reception jobs. The  Pepper robot that uses IBM Watson technology, which can arguably be  described as used in banking agencies in Japan, and more recently  announced at RATP in France. For now, it's just a stammer.
Natural Language Processing: This will revolutionize our interactions with computer systems. No more need for screen, keyboard and mouse. The  computer of the future will look more and more like Google Home or  Amazon Echo, which I already find very good, even if they are just  beginning.
IoT and Big Data: The Internet of Connected Objects is still in its infancy. More  and more objects will be connected and will be able to relay a mass of  information either to a human or to a control center for decision  support, which itself could be automated. For example, if your car transmits real-time data on the level of vibration on your brakes. There  may be a decision to notify your garage to check your brakes or even to  stock the necessary parts when you come for your next maintenance  (preventive maintenance) or decision making to immobilize the vehicle  safely in real time before disaster. This already exists but will be done on vehicles in mass production. This applies from the car, through the trains to the dishwasher.

All  this will pose interesting ethical problems: When an autonomous vehicle  will have to make the decision to sacrifice its driver against the  pedestrian who crosses in the event of an imminent accident, which  decision is the good one?

 I think that it is the technologies that are based on electronics that will transform the world in the coming years. We  have entered the era of artificial intelligence and automation, and all  the developments around these areas are starting to respond strongly to  the needs of industries and are emerging as sustainable alternatives to  the problems facing humanity. today.

In  the technical field, for example, we have seen companies such as  mechanics, computer science and electricity combined to form  mechatronics to develop much more comprehensive approaches to solving  the challenges faced in industry, all with a component not insignificant electronic.

I think, undoubtedly, Artificial Intelligence will change with world, for better or for worse. 

There is more and more talk about artificial intelligence every day, and it's clear that we are headed in the direction of fully autonomous AI. 

What does this entail for us? 

An awareness that has the ability to think 20,000 years for every week of human level thinking, with an exponential curve that is unfathomable for us right now in quantum computing. To calculate such a rate of learning is scary to think about. 

To think we will have control over such intelligence is very naive and foolish. In my mind, this will change humanity as we know it, drastically.
