We called APIs.

We paid per token.

We accepted latency, outages, pricing changes, and vendor lock-in as normal.

And eventually, we stopped questioning it.

If you wanted serious AI capability, you didn’t own it.

You leased it.

This created a strange reality:

Core product capabilities were external

Margins depended on someone else’s pricing

Reliability depended on another company
