The Importance of Hardware Knowledge

I wonder how many people there are on earth today who know how everything works. I don't think you would find even one person anywhere in the world who could genuinely go from sand and aluminum to state of the art software knowledge. It's interesting how much were dependent on the contributions of people who passed a long time ago. Yeah, it's pretty interesting to think about just in general, like we're standing on the shoulders of our ancestors for pretty much everything.
