The truth is that a majority of tech companies don't need 50%+ of their employees. Google could lay off vast swathes tomorrow and be immensely more profitable without any loss in revenue. The 2010s will be remembered as the golden era for tech employment. The second we start getting industry wide layoffs, the insanely high wage inflation we've seen will kick into reverse much faster than you probably believe possible…
A bare-bones, scrappy team makes sense in the startup world but not the publicly traded enterprise engineering world. Move Google back into this world and it'll quickly crumble in a few quarters.
