Ask HN: Where did all the Product Managers go?

The trend towards having no Product Managers in an organization seems to be catching on. Stripe does not have PM folks. Nor does Square to an extent. When hired, the work is split between project management and passing the parcel between various departments of the company - engg/release readiness/sales etc. There was a time when Intuit was the shining star of PM training. Are there good product organizations? It seems like most are sales or engineering driven. And will this field even survive in the future?
