> More importantly, new Product X, whatever it is, helps to attract new top talent. Top Talent is going to want to fix old things, they want to build new.

Is that really true? I would personally chose to work on Facetime than Google's new messaging system, all else being equal.

Facetime is really solid and I'm sure I could learn a ton from the expertise there; as well as working on something new within that product.

In contrast, Google's messaging systems just seem like a mess. I would feel like it could be cancelled at any time, that we didn't have the best talent (because it's spread across the various systems) and honestly would be slightly embarrassed to talk about it ("yeah, I know, yet another message system from Google").
