Also seems like a great idea to create a business models where the companies aren't incentivised to provide the best product possible. Instead they'll want to create a product just useful enough to not drive away users, but just useless enough to temp people to go up a tier, "I'm so close, just one more prompt and it will be right this time!"

Edit: To be clear, I'm not talking about Zed. I'm talking about the companies make the models.
