Amazing fact (to me at least): the first wheels on suitcases appeared in the 1970s. My wife and I, both baby boomers, have asked ourselves: how is it possible that we all dealt with suitcases without wheels all the way through the 50s and 60s? What was wrong with all of us?
And sliced bread first appeared in 1928. I’m not talking about cumulative technological advances here, like computers and cell phones and ATMs.
Still, isn’t that the way with a lot of the really great ideas? They seem obvious. But only after you see them.
Can you help me with this? Can you remind me of some other great-but-obvious ideas?
