My livelihood as a software engineer depends on the existence of computers.
Semi-conductor manufacturing is the most complicated endeavor that humankind has ever undertaken (yes including the Mars missions, read the book Chip War) and it is mostly concentrated in one island nation. Also, it involves critical raw materials that are available in only one location on Earth. It doesn't get more fragile than this.
Meanwhile, the "Cloud" is an illusion of infinite computers on a finite planet.
