You'd actually be surprised at how untrue this is.  There are tons of
devices out there still using 8- and 16-bit processors (or no processors
at all!)  What's happening is that these low-end systems are getting
installed into smaller and smaller devices.  So yes, if you look at a
particular device (e.g. cell phone) it's getting more powerful every
year.  However soon our light bulbs will be "smart".

So let's not assume that these low-end processors are going away, please?
