It is also a bit less easy to throw hardware at a problem when your software is actually embedded firmware. Upgrading or adding hardware reduces your profit per unit. But TBH in this particular field Moore's law still rules.

Yet paying attention about optimization allows you to do more with what you have, or sometimes allows you to use less optimal but more convenient or simpler approaches.
