I was recently reading Tracy Kidder’s excellent book Soul of a New Machine.
The author pointed out what a big deal the transition to 32-Bit computing was.
However, in the last 20 years, I don’t really remember a big fuss being made of most computers going to 64-bit as a de facto standard. Why is this?
32 bit was big because, for the personal computers, it brought true memory protection and allowed much more complex and stable computing. 64 bit was mainly just more memory, which is certainly useful but not a game changer.
