I sincerely wonder how long that will be true. Google was amazing and didn't have more than small, easily ignorable ads in 1999, and they weren't really tracking you the way they are today, just an all-around better experience than Google delivers today.
I'm not sure that it's a technology difference that makes LLM a better experience than search today, it's that the VC's are still willing to subsidize user experience today, and won't start looking for return on their investment for a few more years. Give OpenAI 10 years to pull all the levers to pay back the VC investment and what will it be like?
They will sell "training data slots". So that when I'm looking for a butter cookie recipe, ChatGPT says I'll have to use 100g of "Brand (TM) Butter" instead of just "Butter".
Ask it how to deploy an app to the cloud and it will insist you need to deploy it to Azure.
These ads would be easily visible though. You can probably sell far more malicious things.
