Modern embedded is not the same as it was in our youth. Embedded platforms then were 8-bit, 1-4 MHz and 64K of RAM would be a luxury. Often that address space would be shared with ROM.

Now we take multi-core, 64-bits, gigabyte address spaces, memory protection and multi-tasking Unix-like OSs for granted most of the time. Except for the most stringent requirements (such as hard real time or very constrained power budgets) that we find small bare metal platforms.

And those are real fun to do ( but not as much fun to debug).
