People are being weird about this. ChatGPT has no moat because switching costs are zero. There's no investment into a particular AI service.

ChatGPT has mindshare but that's not the same as it being a moat. The fact that people will continue to use ChatGPT after some gentle frog boiling is true of any service. Adding ads is going to be a measure of how real people tolerate ads more than anything about ChatGPT. Normal people really don't care that much and it bothers me—and probably most of HN.
