Humans by nature are never satisfied with thier needs and they always find it insufficient so they keep on complaining about that.
Realistically advancement of science and technology have provided humans with millions of facilities which they are using.
Actually it is not dissatisfied with needs, but because every need that has been obtained will still be used up over time so that every human being must continue to look for needs in his life and science and technology are tools that can be used by all humans to find the necessities of life that they need and I think it will always give satisfaction to every human being who is able to use it better in his life.
