Imagine an alternate history in which chessboards were always 9x9, but computers were 64 bit as here...

Ouch. I can already imagine all the painful ways in which that would be worked around.

Computers used to be 32bit, 16bit, 8bit...

But 64-bit is enough to represent essentially any value you might care to manipulate numerically, with rare exceptions such as cryptography. Given the constraints and trade-offs of real world computing, I suspect 128-bit will never become the norm.

You might want to look into AVX-512.

Yeah, 512-bits / SIMD computations. If chessboards were bigger, then we'd probably just use the SIMD registers. 128-bit SSE is quite common, and 256-bit AVX has been around for ~5 years now.

Computers used to have 6 bit bytes and 36 bit words...I don't have my mom's IBM 704 manual anymore though.
