When I hear “64-bit” without any additional context, I absolutely think x86-64. ARM64 devices aren’t really that widespread in people’s mindshare, I would wager.

That doesn't mean that's universal, particularly for those of us who remember 64 bit CPUs before x86-64. I'd even wager that very young people stopped associating it with x86 at all since all x86 CPUs, save some Intel holdouts, have been 64 bits for at least the last fifteen years.

It is just the context, those of us who came all the way from 16bit 80286, 32bit 80386 to 64bit will read the 64bit a little differently.

Especially in today's world. Some level of Hardware understanding used to be a requirement. Now a days most developers grown up with abstractions they dont have to care about any of these any more.

Oh, how I do not miss having to attribute pointers with near and far!

As the parent poster said:

> Alpha, UltraSPARC, MIPS and even Power had 64 bit long before the 2001 introduction of the Itanic.

And even PA-RISC had 64 bits. Itanium was just a processor trying to disrupt the RISC market.
