I wish we collectively had a better understanding of those ad tech shifts being fundamentally zero sum.

If we treat marketing as a black box, where are the benefits from supposedly more efficient marketing? Ad budgets are the same. People have the same amount of disposable income (or less, really). So on the both sides of the box converting ad budgets into paying customers the sum is the same. Quasi-monopolistic ad networks (Google and Meta) just hoovered up the money that previously went into other ad spaces, like local papers. Now OpenAI is going to fight for the same pie.

Ad tech is a market failure.
