The real teams here seem to be:
"Team Board That Does Whatever Altman Wants"
"Team Board Provides Independent Oversight"
With this much money on the table, independent oversight is difficult, but at least they're making the effort.
The idea this was immediately about AI safety vs go-fast (or Microsoft vs non-Microsoft control) is bullshit -- this was about how strong board oversight of Altman should be in the future.
Microsoft can and will be using GPT4 as soon as they get a handle on it, and if it doesn't boil their servers to do so. If you want deceleration you would need someone with an incentive that didn't involve, for example, being first to market with new flashy products.
