Before I even made that post I knew you would respond, you love me really.
I think as technology improves we will come to a point where many common items will be hard to improve upon, will become more efficient and last longer, and I believe there will not be as many evolutions of certain products,=
At this point in time I agree, and it will continue doing so for a while yet, but I think eventually technology will provide so many of our needs that it will slowly force us to look that those very desires we have for material wealth, it will be a gradual process over many decades/hundreds of years, technology will continue to get cheaper, many items we see as luxuries today will be common place and cost next to nothing, I think technology pays a vital roll in our development as a species.
