From a business perspective, its worlds different. Snapchat (say what you will), with its multi-billion dollar valuation, wouldn't have existed until we had the ability to get internet from a toilet stall with a pocket-sized device. My company, a SaaS for farmers, would not have been as valuable to our customers had mobile devices not been around, and people still had to use dial-up.

The internet used to be a bunch of usenet forums for geeks, now everybody uses it to some degree, which means that lots of businesses with real-world value are possible where they weren't before.

For crypto, anonymous payments, speculation trading, and currency exchange are the immediate innovations, but the Facebooks and Ubers of crypto have yet to be created.
