This is what OpenAI and Anthropic are trying to make everyone believe. Most accountants will flinch at this (they already are).

The $200 odd plans are already out of reach of many, many people.

The attrition of customers if they were to get rid of these subscriptions plans would be untenable.

I think you are looking at it incorrectly. No business is buying individual accounts, because if they do, they open themselves up to considerable risk.

The $200 plans are priced so that the power-users use them and then advocate about how great the product is. If you're buying a $200 plan, you're not doing it because of the price point but rather because of the amount of work it is doing for you.
