In software, we turn late nights of coding, caffeine, and ideas into things people use. The sum total output of our work ends up being sequences of 1's and 0's on magnetic platters. And those sequences can be copied instantly and infinitely for virtually no marginal cost. What the Internet brought was the ability for those sequences to be sent everywhere around the world for free.
Virtually every other industry involves taking atoms of some form and rearranging them into atoms of another form. There are a finite number of source atoms, and those atoms invariably cost money. It also takes real people or machines to do the rearranging, aka product assembly. And it takes real time, measured in minutes if not hours or days, not microseconds. Once the atoms are in a final state, the show's not done. The final arrangement, aka product, must be shipped to customers, aka distribution. They've got to be stored someplace, and that's not cheap.
The conceptual difference between having a business based on atoms and electrons is astonishing. People who arrange, create, and ship electrons for a living should be thankful. I know I am.
Edit: The actual difference between an atom and electrons is a nucleus.
