There is no security. You never know when things will go wrong. When pandemic happened software companies like Twitter were untouched but millions of workers felt its impact shaking them to the core and hence preparing them for better choices next time. The employees that are laid off I wish them best of luck but they should have been prepared for a day like this. They were earning good. It's things like this which transforms people. Maybe someone out of these employees will start next billion dollar company, who knows?
