The industry at the time was wanting larger CPUs than 8 bit. Intel had an
existing 8-bit design, the 8080 and to fill demand, Intel had a few choices.
It could break with any form of compatibility (object or source) and start
over with a clean slate . Or they could keep some form of compatibility
and Intel went with (more or less) source compatibility. You could
mechanically translate 8080 code into 8086 code with a high assurance it
would work, and thus customers of Intel could leverate the existing 8080
(and Z80) source base.
And that's how you end up with a bizare segmented 16-bit architecture.
 Motorola took this approach when making the 68000. It's nothing at
all like the 6800.
