> You say that as if you believe Google will never have a hiring freeze.
No, I don't. The discussion is about Google's current state, and Google current plans to deal with diversity given that current state. A change in circumstances (and Google going from "hire every qualified person we can get our hands on" to "stop hiring anyone" would be a radical change in circumstances) would be an occasion for a different discussion.
> Are you really that naive to think Google will continue to expand indefinitely?
I think that Google's concerns about and options for approaching diversity would be different if Google was funding or task constrained rather than employee-pool- constrained, and that the proper focus of discussion is the real world that exists, not some speculative future that may or may not exist in the lifetime of anyone discussing it.
> They absolutely will hit a point when they can't just leave the number of new hires uncapped.
Its almost certain that sometime before the end of human civilization that that will happen for Google, but the time to discuss whether diversity should remain a concern and what steps are appropriate to address that concern in a funding-constrained firm will be appropriate with respect to Google when that occurs. However, it isn't the case now, so its just a distraction from the issue today.
Especially since I'm sure that -- as much as Google would hope to avoid that circumstance as long as possible -- Google would also prefer to acheive an acceptable demographic profile in its workforce before it becomes constrained in that way (and, insofar as there are business as well as humanitarian reasons for its diversity concerns, sees acheiving a good diversity profile as part of a strategy to continue growing in a way that does not result in them becoming resource- rather than employee-constrained.)
