Embedded systems don't really scale the same way backend systems do. In embedded, you write the firmware, and it gets loaded into thousands or millions of devices. There may be a few updates, but firmware kind of gets frozen in time.
With backend, you write code that can be used to expand a business. You're adding features to grow marketshare or scaling up to meet user demand, so it has a more direct correlation with the health of a business. It's less of a cost center, and more of an investment.
