Necessity isn't the mother of all invention...

random rant:
Necessity isn't the mother of all invention...
We sure as hell didn't think we needed flight when we came up with it. We wanted to go someplace where 'everyone' said wasn't possible..."to go where no man has gone before", whether its in exploration, academics, religion, music, art, physical accomplishments, etc.... People are still trying to be the fastest runners in the world, every year....

Necessity isn't the mother of all inventions, ambition is. And this is important to point out, I think. If you thought of something new thats cool and want it done, then ideally, that desire shouldn't be hampered by asking if its necessary or not...( realistically, safety and practicality matter =P. )
We don't invent things because its needed, we just hold onto the inventions that we feel are necessary ( and usually pick the ones that are deemed safest and most practical).
