. Clarifying: all of the projects I was involved in & driving at Google (incl. S4TF, MLIR, an incredible new TF runtime, XLA, TPU SW, etc) are in very good hands 
, have exec commitment and strong roadmaps. I c/wouldn't leave if uncertain about that! @JeffDean
With Swift, LLVM and other projects, you've clearly proven that you have what it takes to leave a project in capable hands and to ensure its long-term success, even as you move on to new things - so I'm not worried, just excited for you 
Best of luck on this new adventure!
