So I started at Google in 2020 (after Sam closed our lab down in 2017 to focus on OpenAI), and if they were hoarding it, I at least had no clue about it. To be clear, my perspective is still limited.
LaMDA is probably more famous for convincing a Google employee that it was sentient and getting him fired. When I heard that story I could not believe anybody could be deceived to that extent... until I saw ChatGPT. In hindsight, it was probably the first ever case of what is now called "AI psychosis". (Which may be a valid reason Google did not want to release it.)

That sounds like something execs would say to fend of critics. "We are #2 in AI, and that's all part of the plan"
