Changing one's job should not be considered as tragedy
Everyone, literally everyone in IT industry should climb up from their pits of comfort and change job at least once in a decade, or else they'll stagnate their personal development and eventually may end up becoming unemployable due to obsoleted set of essential skills. These news of big techs letting tens of thousands go may sound terrible, but there's currently high demand for skilled professionals and in the end a change will do good for all the involved parties.
