Google could cut at least 30-50% more of staff and be just fine. They need to shut down their "moonshots" as none have yielded any appreciable return for shareholders. Just shut them all down, starting with Waymo. Focus back on the core business: ads. Get rid of anything and everything that doesn't directly contribute to serving ads. Do away with all the cafeterias, maker spaces and the ridiculous swimming pool and restaurant on their campus. Shut down the kitchens and replace snack areas with vending machines.

I also think Google could get away with paying employees a lot less. You don't need to be a genius rock star to serve ads. They don't need the top of the market, and in fact it has been shown that strategy has failed them as a business. Shut down anything & everything that isn't making money TODAY.
