I think that some issues that are here today, are here only because of the politicians. We could solve so many problems if they don't have that much power, over resources and over people. That is the sad part of almost all issues in the world. If you remove politics and give the problems to people who are solving them instead of talking about them, then we could have a much better world than it is today, much more sustainable.
Technology is growing fast, and sometimes we cannot control it. But, I see future in the things you talked about here, the drones and VR... If they can save lives, I see the future there. Don't forget that life is the most precious thing we have. ;)
If we give a really good education to doctors about this, I wouldn't mind be a patient. But, our education system is wrong and it must be changed, so I'm more worried about that.
Thanks a lot for sharing good knowledge, I also don't like to go to doctors, but it's good to know about this things, about the future. Have a great day, Luka.
