Bosworth: Consumers will soon treat AI models like invisible database infrastructure
“The model itself isn't the value. And I think we're going to get to a world very soon where consumers, they don't care. They don't want to specify the model they're using. They don't want to, they don't care if it's 4.7 or 4.8. Like you don't care what Oracle,…”
