Thank-you a lot for that. I wander around the tech blogs like lobsters etc, Reddit and here but never see anything that i remember seeing (if you follow me), but I don’t consciously look.
Encryption lengths are getting long so you’d think it was high time.
Your description sounds like the advent of 32 bits where there was a 16 bit address bus stage.
I started out programming a 6502a in 1980, 680X0 a little later in 87, so I get that bit, but it’s easier doing operations on a larger register. I remember writing code for 8 bit multiplication of 32 bit floating points.
I enjoyed and understood the rest of your prose though. Didn’t do much/any programming/low level after say 2005, and regret it now. Trying to re-learn but things have moved on so much.
I take that there isn’t much motivation in moving to 128 because it’s big enough; it’s only 8 cycles (?) to fill a 512 (that can’t be right?).
