Technology That We Would Uninvent If We Could

First of all, technology is important now in many things. But there are some of that not successful in this
time like cloning technology. They are trying to return back some animals that imposable to do like dinosaurs.The truth is that technology wast too much money for some thing imposable to improve.
I hear about the people who want to cloning themselves but what the advantage from that. Would be better if they spend the money to help the people dieing from starving and diseases in poor countries.
To me that technology wasting time and money for nothing.     

If i were president of USA

I would try to make the gas prices less than what they are now. Because some of the adult that have children need to get to work everyday. Also i would invest to make more schools, playgrounds, daycares, and alot of other stuff too. The one thing i would do is meat with other countries that is having a hard time with their life and i would try to help them in any way I can. I would make a law saying there be less homework and parties everyday to remove stress out from worker who work a lot with out enough salary.
