Leaders sounding Grovian culture/approach is not going to work. Leaders need to come with their original approach. I am starting to think no leader is truely going to execute the company in the founder's style. There are multiple issues with that (a) today's leaders have not understood what is Grovian style. (b) Problem domain was completely different in founder's time. So, do not try to replicate/mock now those style and expect that to work.
That's the primary reason many big corporates lost their glory times i.e. IBM, Motorola, Sony etc. Once the founder is gone, the next gen leaders have no idea how to sail the ship. So, roughly 40 years after company is founded, the innovation will die out. Hence the company will see the fate like we see now.
