You seem to have blinders on when you speak of "improvements". Don't you see the destruction that has occurred in our history? Don't you see the need for REAL "improvements" that are far from reality in our present plight? Things are NOT good for humanity at the present time. They might be in the future (let's all hope they are), but I can't buy into this "continuous improvement theory" of yours. We have not been into that mode... sorry! Perhaps some of us have seen an "easier life"... and we are kidding ourselves into believing that it is "better". But, if we are really honest with ourselves, even our "easier life" has many negative aspects for even ourselves, let alone the natural world, and the majority of people in the civilization that has been built on this planet. I think your logic is too simple to say it is always about "continuous improvement". Cuz it's NOT!
