I learned about economy. World's economy changed over time, In particular, in world 1,2 war economy decreased rapidly. And I learned about technology. We live with many technologies. The technologies give us good advantage. But they may give us disadvantage.
It is estimated that world's supply of oil will run out within about 50 years. What consequences may it have on our society?
I think that if oil runs out within about 50 years, we will develop alternative energy. We need oil.
But if oil doesn't exist, we look for something to alternate oil. However, oil occupies most of life.
So alternative energy can't be substituted with oil perfectly.
Maybe something to use oil will stop for a while. Our society may fall into utter confusion.
Before oil runs out, our society will be like war. Because people with money stock up heavily with oil. After people develop alternative energy and popularize technology, our society will be restabilized back.

How will the technology change our lives in the future?
We had a discussion about 3D printer, 3D printer will give us many effects.
First, we can work with little effort. Hard work will be done by 3D printer. Also we can decrease time and cost. 3D printer can save product's information. So we use the memory. Therefore, time to make product's information will be saved. Second, in contrast 3D printer has bad effects.
Because of 3D printer, people will lose their jobs. Originally 3D printer's work is person's work.
3D printer will lose people's jobs with cheap cost. Also people may be lazy.
Because 3D printer do person's work, we will not begin to pay attention about work.
The technology will change our lives in the future. But the technology don't have only good thing.
So we must choose something to need in our lives. If we don't consider disadvantage, we have advantage just now but later may have disadvantage.

I also think right before oil runs out people who have lots of money will buy in some oil and that would be alike war. I wrote advantages of 3d printing but I also agree with your writing of disadvantages of 3d printing. But I think still 3d printing's innovative technology can't be neglected.
