In my opinion, jewelry will lose its value because of the new 3D printers able to make anything look like anything, meaning that people that work on 3D printers could make a solution that could have the same heat distribution as dimonds.

o ouro e a mão de obra humana

in my opinion workers,because now we can see that some work do machines,and in future workers might replace to robots(machines).

I think the latest technology because there will be newer and better technology in the future. Gold may also lose value in the U.S. because of the dollar's rising strength and it may also lose value because gold miners produce more gold than what people want.

How worth it is depends on the valuable description, which created by economist, market and advertisement. Diamond and rock are all stone, but some sparkle fancy story made Diamond very valuable, which will become worthless if it lose makeup by economist, so as Gold.

I think they might be gold.

PURPLE

I think meat because people are finding out ways to make meat that tastes like and looks like meat with vegetables. Even though we value meat very much, in the future, a lot of vegetarian meats will take the spotlight of real meat. Actually, getting rid of meat can save the environment since the land to supply feed and shelter for those animals has a massive land amount in total, almost as big as in Africa. Also, if cows are gone, then we can get rid of a huge source of a harmful greenhouse gas, Methane.

i guess technology, because it will be upgrade in a few years later from now and always continue to be upgrading. people always interested for new technology that might can help in everything.

Jobs in current generation. I think it will be replaced with robots/AIs, such as manufacturing workers, drivers (self-driving cars are now developed), service jobs (such as waiter & bartender), and many more.
