The digital revolution

One by one, the digital revolution has swallowed whole industries. Anything that can be turned into information eventually is — and the incumbents rarely survive the transition. For decades, only one thing held out: money. Bitcoin is what happens when the revolution finally reaches it.

The track record is unambiguous

🎵 Music

Records and CDs → MP3s and streaming. The physical format vanished.

🎬 Hollywood

Video stores → peer-to-peer and streaming. Blockbuster is a meme; Netflix is a giant.

📷 Photography

Kodak invented the digital camera, then was destroyed by it. Film is a niche hobby.

🚕 Taxis

Medallions and dispatchers → an app. Uber and its rivals rewrote the industry.

🏨 Hotels

Airbnb turned spare rooms into the world’s largest lodging network, owning no hotels.

📞 Telephony

Copper lines and per-minute billing → VOIP. Calls became just more internet data.

📺 Television

Broadcast schedules → YouTube and on-demand. Anyone can publish to the world.

💬 Connection

Classifieds and matchmakers → Tinder, social apps. Even meeting people went digital.

Why money was the last holdout

A song is useful even if it’s copied a million times. Money is the opposite: it only works if you CAN’T copy it. As we saw in the Computer Science section, a digital file duplicates perfectly and for free — which for money means counterfeiting and double-spending. That single flaw is why, while everything else went digital, money stayed trapped in banks and central ledgers. Digitising money meant solving the one problem digitisation usually creates.

The question that hangs over this whole section. Every industry that met the grassroots digital revolution was reshaped, and the gatekeepers lost control. So what happens when the revolution reaches the most guarded gatekept thing of all — the money issued by banks and governments?

The answer wasn’t built by a company or a government. It came from a fringe movement of privacy-obsessed programmers who had been trying to build digital cash for two decades: the cypherpunks.
