Earlier quoted context omitted.
I think the point is that they hoarded the technology for internal use instead of opening it up to the public, like OpenAI did with ChatGPT, thus kicking off the current AI revolution. As sibling comments indicate, reasons may range from internal politics to innovator's dilemma. But the upshot is, even though the underlying technology was invented at Google, its inventors had to leave and join other companies to turn…
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.)
