What is the greatest invention since the year 2000?
It depends what one considers an invention. Computer, biology and similar inovations are merely progress and not strictly inventions. They are the result of trial and error based upon prior works over many years. I don’t know when Velcro was first produced but I think it is before 2000, but that might be considered a true invention. However, in actuallity a plant developed a method for reproduction (a method used by other vegetation) and a human was able to replicate that method. A true invention is when someone develops a viable method to solve a problem without input from prior attempts or develops a method to just make life easier that no one else thought off.
