So social media, railroad, the bulb the internet and e-commerce. What is the one thing all of them have in common? They’re all copies of existing things. They’re not original ideas. Social media is a copy of the high school yearbook on the internet.

E com is just a copy of the print shopping catalog. Moved to the internet and the bulb is nothing but transfer of energy over the electric wire instead of wax and thread. And the internet is extremely old people in Roman times going back to Roman times, different towns on opposite sides of the hill would talk to each other using signal flares.

And your optical fiber is basically that signal flare inside a cable and railroad is just the invention of the track. which can go to places roads cannot go using the wheel which existed before. So innovation is mapping of old stuff on newly created networks or pathways.
