Money, and why it sometimes goes round in circles

Part of the AI news cycle isn't technical but financial, and it requires its own reflexes. This lesson gives you three of them.

Reflex 1: distinguish the announcement from the spend

"A $100 billion investment" covers very different things: money already paid out, a ten-year commitment, a letter of intent, or a valuation of assets that haven't changed hands. Always look for how many years it spans, and what's already been disbursed. The gap is often an order of magnitude.

Reflex 2: spot when the money comes full circle

A pattern keeps recurring. A chipmaker invests in an AI lab. That lab uses the money to buy chips from the same chipmaker. The chipmaker books revenue, its value rises, which lets it invest more.

Nothing illegal here, and these structures have real justifications: securing a supply chain, guaranteeing a customer. But the revenue created this way isn't external demand. It looks like growth, but isn't quite.

Reflex 3: the bubble question, asked properly

"Is it a bubble?" has no simple answer, and it's a genuinely contested issue among competent people. The two readings:

• Yes: investments far exceed realised revenues, part of the demand is circular, and tech history is full of infrastructure built too early.
• No: usage is genuinely growing, so are revenues, and oversized infrastructure remains useful later. The cables laid during the internet bubble served for twenty years.

Note that both sides can be right: a financial bubble and a durable technology coexist very well. Many companies can disappear while the technology takes hold.

What this means for you

Concretely: don't build your work on a free service whose provider loses money on every request. Prices go up, free tiers shrink, services shut down. Keep your data exportable and your workflows transferable from one tool to another.

Key takeaway: when you read a figure, look for the timeframe and the share already paid. Those two pieces of information change the reading more than the figure itself.
