slow tech

Kind of crazy when you think entertainment went from sound w/o video (radio) to video w/o sound (earliest TV) to TV w/sound w/o color, to today's TV.

What I mean is like, you are sitting there watching a silent show and you are ok with it because it's normal. Then someone adds sound, but it's ok that it's black and white because it's normal.

I assume between each entertainment era there were scientists/inventors constantly working on the next step. But if you think about it, everything we ever needed (matter) is right in front of us. It just seems to take us a while to get from one step to the next, figuring out what to do with the matter. I wonder if that's based more on human mental capacity, or consumer demand.

We have big dreams of moon colonies, interstellar flight, and a cure for cancer. Why can't we just do them today? Are we slow thinkers that have to sit around for X amount of time pondering solutions? I bet if every adult on earth united every resource toward curing cancer, we would at least know within a month or so if it can be cured at all.
