This seems like it will result in a much more costly on-boarding process new employees. Currently, if you hire some freshly minted phd to work on ML stuff, chances are they have read most the specialty's relevant cutting-edge research. Moving forward these same phds may have to spend months learning your fancy model architectures just to be somewhat useful. Hopefully at the end of that extended on-boarding, google doesn't find out their new hire is a complete dud. I guess if you have money, burn it. Plus, if I spend years working on research at Google only to be unable to take those skills with me to my next job... well I wouldn't say yes to that job in the first place. Why not put a big sign on the door that proudly reads "lifers only"?
