People who can pay to use the best models will start pulling away from those that can't.
You already see this with the engineers who can afford to pay $200 a month for Pro/Max plans.
Recent grads probably can't stomach paying that much.
The people who already have enough resources to be able to pay that cost without thinking will pull ahead.
This happens fractally down the stack.
The engineers who can use Fable-class models vs Opus-class.
The people who can use Pro/Max vs the people who are just paid ChatGPT subscribers.
The people who are paid subscribers to the chatbots vs the people who are on the subscription plan.
The people who can use the better model before others have superpowers.
