Q & A

Q: How do you think about Perplexity AI?

A: I feel ChatGPT also has the same capability. It has a browser plugin and it also starts with a chat.

Q: What is the difference between perplexity AI and OpenAI?

A: Perplexity AI focuses on search and optimizes the user experience, while OpenAI focuses on being a platform and wants others to use its capabilities to build other things.

Q: What is the relationship between Rivian and Tesla?

A: Rivian is a smaller company that is more focusing on one specific area and trying to be the best in that, while Tesla is a larger, more comprehensive company that's maybe 90% good at everything.
