That's a good point. Google was sleeping on AI and wasn't able to come up with a product before OpenAI and they only scrambled to come out with something when OpenAi became all the rage. Big companies are hard to budge and move in a new direction.
Google and Microsoft have existing major money printing businesses to keep their AI business afloat and burn money for a while. That's how Microsoft broke into gaming (and then squandered it years later for unrelated incompetence)
You can say it about the AI companies, but Google or Microsoft are far from AI companies.
