The board will bring in an adult CEO who can balance the nonprofit charter with Microsoft and the commercial business, and who doesn't have a million side projects taking his or her focus away. Some employees will leave but the vast majority will stay for the usual reasons (i.e. inertia), the business will keep growing because ChatGPT is already a worldwide brand at this point and the vast majority of users don't give a hoot about any of this palace intrigue as long as the product works.
And the board will ultimately be vindicated for acting as fiduciaries for the nonprofit's mission and bylaws -- and not for the financial interests of Satya Nadella, Vinod Khosla, and the like.
It is to be seen if investors will likely pour another set of billions of dollars, just to catch up to speed with OpenAI, which, by that time, would have even further evolved.
There is a ray of hope that, as it so happens in this field, that old things are quickly obsolete and new things are the cutting edge, Sam Altman can convince investors to invest in the cutting edge with him. Then investors have a choice on an almost level field, to choose between people, companies and personalities, for a given outcome.
Sam will get billions of dollars if he starts a new company. So there's no issue of money. In terms of data and training models, look at Anthropic - they did train a reasonable model. Heck look at Mistral, a bunch of ex Meta folks and their LLaMA team lead who spinned up a good models in months.
The only bottle neck i could think of would probably be RLHF data - but given enough money, that's not an issue either.
