Very thought provoking reply. #3 sounds the most sticky to me, in the product sense that you'd build "your own LLM/agent" and plug it other services. I heard this on a product podcast [1], think of it like Okta SSO integration: access controls for your personal/sensitive LLM stuff vs all other services trying to get you to use their LLM.

#5 stands out as well as a substantial barrier.

The rest to me our sticky, but no more uniquely sticky than any other service that retains data. Like the switching cost of email or a browser. It does stick but not insurmountable and once the switch is made, it's like why did I wait so long? (I'm a Safari user!)

Anyway, thanks for the thoughtful reply.
