I seem to remember similar sentiments around APIs. Obviously companies realized that open APIs aren't great for maximising profits. As long as blocking bots is possible, bots that serve the users will be blocked. The reason the interfaces suck right now is not that the companies are bad at interface design. It's that user friendly interfaces are less profitable. Imagine if I said, “I will only shop at grocery stores that don't intentionally reorganize ever 2-3 years to make it harder to find what you and that don't intentionally hide eggs and milk at the back”. I would simply not shop a grocery stores. Such a store would be objectively better for the customer but would be less profitable. Agents may come. In fact, I won't be surprised if they do. But they will not serve the users. That isn't a profitable play. Agents will serve Zuckerberg, Musk, Altman, etc.
