Jensen should start a new company and hire them. California's ban on non-competes is one of the few good laws it has and made Silicon Valley what it is. Time for another traitorous eight.
Even with patents, copyrights, etc as mentioned in a sibling comment, it would be interesting what he could do if he had a fresh start. There might have been ideas that challenged the existing business that he could be free to pursue.
He'd have no shortage of talent and funding to embark on such a venture.
The big question is once the dust settles (including a possible divorce), he'll still have billions of dollars and need a reason to get out of bed. Being that he's a famous workaholic, I imagine he will try something new after he's done licking his wounds.
That company would suck because it wouldn't own any NVidia patents nor the copyright to their software and it wouldn't have the contractual relationship with TSMC that NVidia has. Nor their customers.
