Of course that makes sense. I wasn't thinking in the context of the
original post.

I guess this underscores for me the illogical notion of 32 bit MCUs
'killing' 8 bit.
32-bit may provide for quicker development if you want to write in C
(and there's talk of C++ at Microchip) but at the most basic level the
ALU of a 32 bit chip is always going to be switching more gates than
one with fewer bits, thus using more energy per cycle, if you care
about battery life.
