What kind of repercussions will OpenAI face?
Based on a cursory read of the situation, it seems similar (at least on its face) to the Waymo vs Uber situation. In that case, Uber payed a Waymo an equity stake and signed an agreement about which technology they would/wouldn't use. The key person involved also was sentenced to 18 months in prison (pardoned after 6 months).
Basically nothing. I mean they’ll have to pay up but money clearly isn’t something OpenAI worries about. They’ll just raise more from the infinite vc money tree.
Apple may get a chance to rifle through OpenAI's trade secrets. And they may win an outcome where there is direct court supervision over what OpenAI is allowed to build and how.
In the extreme case it may result in OpenAI having to abandon their in-progress consumer hardware products, but honestly that might actually be good for them. I really can't see all that investment being worthwhile. Better for them to stick to their core competency.
More realistically - OpenAI will cooperate, the specific employees involved will be punished, there will be a settlement, and this whole matter will be forgotten.
