I was making the point that just because something is 'recent' doesn't mean it isn't necessary and we can go without because 20-50-100 years ago it wasn't needed.
The world changes. I travel all over the world for business. Contracts that I couldn't do without that travel. Just because 50 years ago I wouldn't be able to do it, doesn't mean it isn't necessary now. (Same as internet, just because 50 years ago you didn't need, or have, the internet, doesn't mean nowadays is an integral part of business)
