The question is what they plan on doing with all their scientific knowledge once they succeed.

Sure, they'll keep it internal for a while to make sure their knowledge bank is more thorough than everyone else's, and because oftentimes discoveries can be far more convincing internally than externally (you need fewer sigmas for it to update your belief in a certain direction). But then how do they intend to profit from it in the end?

Maybe a little naive for this but given the decades Jeff Dean and Sanjay have been contributing to so many things in the industry and never heard a bad word about either, they never seemed to reach for attention or self promote, going to give them a little more of a cachet of trust.
