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.
