Great Inventions in the Past 20 years

Here is a list… ahh the heck with it. I was talking to some friends here and really sick of hearing about all of the great Chinese inventions,most of which pre-date Jesus, or at least pre-date anything since the invention of electricity. So I was researching just how much has been invented in the past 200 years or so and before. Realizing the futility of this I basically reaffirmed my stance that for the past 500 years China has been a net taker of resources and has not given much back. I know this sounds harsh but forget the emotion of it and analyze. The Chinese will say the fault is of this dynasty or that one, but the bottom line is that they do have over 20% of the worlds people and there must have been some of them who did something that helped mankind
