Google also has $100 billion in profit each year from it's core business to wait out OpenAI.
The more they emulate ChatGPT's clean UI, the more they are failing to push ads in people's faces, which is what generates that $100B for them.
Their business model fails if their users don't experience a confusing crap-fest of ads.
I bet you OpenAI will implement ads far sooner than Google can hypothetically run out of money.
Won't be long until chat AI will include sponsored products and services in the output.
