It’s internal culture that devalues maintenance and product improvement. Launch gets you promo, maintaining gets you laid off.

I saw a lot of humble and dedicated engineers get laid off in the first round and it was a lot of people who put systems stability over their own promo. There used to be a place for those people, which is part of what made Google a decent place. That’s gone now, things will continue to break as long as fixers take the brunt of lay offs.
