Most of the largest tech players today (including Microsoft and Google) did rounds of layoffs in 2008. Of course in those cases it was more trimming some fat rather than a do or die situation. But there are plenty of companies that have survived existential crises of this nature and come back stronger.
I should have worded that better - was trying to think of startups (or companies with startup characteristics (like the high losses and increasing costs coinbase had last q)) coming back after a very large reset.
