I'm not saying you're wrong.

What I'm saying is that segmentation can't be ruled out.

And it may go via that route for the same reason the 8086 went through that route - to maintain compatibility with an 8-bit CPU that is currently in active use running an OS like CP/M.

In fact, after sorting out the standards for an MSDOS-like OS designed to run on 16:16 (with an eye to 32-bit flat), we should probably standardize on a proposal for 8-bit CPUs, to prepare for the 16:16.

Note that there was a bridge from MSDOS 1.0 to MSDOS 2.0. MSDOS 2.0 introduced a radical new API.

I personally haven't traditionally concerned myself with bridges.

But I do note that when people didn't have proper bridges (68000, OS/2, Itanium), they tended to fail.

As much as people turn their noses up at 8086 segmentation and point to the 68000, that's not what happens in real life.

Note that in real life I predicted that the Amiga was going to replace the PC because it was much better, and I personally made sure my C90-compliant programs ran on both MSDOS and the Amiga (I owned both).

But my personal philosophy, and my personal prediction, turned out to be total flops when it comes to what meatbags do.

Oh, I ran OS/2 2.0 for quite a while too, getting software to run on that. :-)
