You don't need 64-bit doubles for signal or image processing.
Most vector/matrix operations on streaming data don't require
them either. Whether SSE2 is adequate or not to handle such data
depends on the application.

Sure, and for that matter, AI inference uses 8 bit and even 4 bit
floating point.  Kahan on the other hand was interested in engineering
and scientific applications like PDE solvers (airfoils, fluid dynamics,
FEM, etc.).  That's an area where roundoff error builds up after many
iterations, thus extended precision.

"Industry" can manage well with 32-bit floats or even smaller with
non-standard number formats.

Depends on your notion of "industry".
