Google's strategy was to keep it in the lab, because they didn't need money and they were winning. It was best strategy for them to just keep going forward while others where sleeping.
OpenAI's strategy on the other hand was to publish old technology as new, make bold claims about AI and get some investors money. OpenAI needs money because they don't have much skills and the only way they know to improve AI is to put more hardware and data behind it. For them, this strategy was optimal.
Because OpenAI went public, Google has to follow, just to show the world who the true leader is.
Beause Google went public, OpenAI is now starting to look pretty bad in comparison. This might not be obvious yet to the general public, but to those who understand the scaling problem and look at the results, this should be visible already. As OpenAI will hit the limit of hardware, they can no longer compete against Google. I expect that they will crash within few years, due to running out of funds.
About the job loss, I am 100% certain that that will happen, but I think that it is unlikely that all workers will lose their job. I think we will see something like 50% of doctors lose their job after something like 20 years, because it will take very long to get approval for new systems on the medical field and most likely we still need people who can evaluate these tools. But even if some jobs will remain, we will lose so many jobs that we will need some kind of reforms.
