I think you're underestimating the power of a fresh start and the potential for ChatGPT to carve out its own niche in the market. Meena and Lambda may have their own strengths, but they are also weighed down by Google's reputation and regulatory constraints. ChatGPT has the opportunity to differentiate itself and appeal to users looking for a new and innovative search experience. Plus, it's not as if Google has a track record of successfully copying and monetizing other platforms (just look at Google+). Don't count ChatGPT out just yet.
