Ian Goodfellow already has come up with the next great DL architecture. So its possible he will do so again.

edit: thinking about your question more-as an AI person I think the business logic behind hiring AI research talent if you are FAANG is not that they are going to deliver much business value in the next five years but they may deliver astronomical returns in the next 25 years. when you have the financial strength of google hiring these people is not a very large risk.
