If the entrenched giants (Google, Microsoft and Apple) catch up - and Google 100% has, if not surpassed - they have a thousand levers to pull and OpenAI is done for. Microsoft has realized this, hence why they're breaking up with them - Google and Anthropic have shown they don't need OpenAI. Galaxy phones will get a Gemini button, Chrome will get it built into the browser. MS can either develop their own thing , use opensource models, or just ask every frontier model provider (and there's already 3-4 as we speak) how cheaply they're willing to deliver. Then chuck it right in the OS and Office first-class. Which half the white collar world spends their entire day staring at. Apple devices too will get an AI button (or gesture, given it's Apple) and just like MS they'll do it inhouse or have the providers bid against each other.
The only way OpenAI David was ever going to beat the Goliaths GMA in the long run was if it were near-impossible to catch up to them, á la TSMC/ASML. But they did catch up.
