A lot of ideas are obvious once somebody announces what the idea actually is. Honestly, I think that people who would criticize the inventor simply because of the idea's apparent simplicity or obviousness are being rather snobbish, if you ask me.
But hey.... some might find it comforting to think that such values, which might otherwise seem outdated in today's word, are still alive and thriving in our society.
Reminds me of a conversation I had with my boss the other day.
Boss: Why did it take 2 days to write about 100 lines of code? That should have taken an hour or so.
Me: The same reason it took you 3 months to write a 10 page grant proposal and not the 30 minutes I could retype it in.
