I get the impression from your writing (and others in this thread) that you feel Google owes something to it's employees other than adequate compensation and a mutually acceptable working environment. That's not how (US) companies work. The CEO has obligations to the board of directors (to run the company in a way they approve) and to the shareholders (to be profitable). No obligation exists to employ as many people for as long as possible, particularly when to do so would impact the aforementioned actual obligations of CEOs. This is why layoffs happen.
When labor is cheap and business is booming, you hire. When labor expenses increase or business declines, you fire. Sometimes that means layoffs to hit quarterly goals. Sometimes that means your five year strategy has a pandemic and economic downturn happen in year three and you have to downscale. The CEO has to take responsibility for that, as he does for everything the company does, but any apology relating is simply a socially graceful admission he lacks omniscience.
(Edit: Before the obvious replies of "but but Google stock is already down 30%", the whole market is down over the last year.)
Is this really true? For software devs specifically I don't think it's common for someone to get fired when they ship code with a bug in it. Or when they make a production change which causes an outage, even if that outage costs millions of dollars in losses and an untold amount of reputational damage.
I'd hate to work somewhere like this. When you fuck up, you take responsibility, you fix it and you ensure no one can fuck up the same way. You don't just fire people who fuck up, or people won't ever do anything for you.
What's should happen, but it won't is that the responsibility for hiring too many people and facing a change of perspective should be to have to keep these people event if it means a decline of profit, as long as they don't face bankruptcy they can take the loss and move on.
That's why there are labor laws and worker unions, so the asymmetry can shift a bit to the employee side.
But he didn't say he got it wrong.
He kinda did.
