What is Google's last successful new product — home-grown or acquisition?

Define successful any way you see fit.

I like Bard a lot, and Gemini is about to make it an order of magnitude more powerful. All their TPU stuff is solid, and their Coral TPUs are great for embedded ML work. They have solid GCP offerings. Chrome, Kubernetes, Tensorflow..

Google created Passkeys, which is something I've seen you talk positively about 😁
