FYI -- "Will you still need me, will you still feed me When I'm 64?" I've now lived through: decimal computers (IBM 1620, IBM 1401) 36-bit/15-18bit-address computers (IBM 7040, IBM 7090, GE635, PDP-10, DEC-20) 12-bit computers (PDP-8) Microcoded machines (Xerox Alto, Lisp Machines) 1-bit computers (ICL DAP 32x32x1 "square word", Connection Machine) 4-bit computers (Intel 4004) 8-bit computers (6502, Z-80, 8080, 8051 (still used inside "USB flash drives"!), 6800, etc.) 16-bit computers (PDP-11, Moto 68000, 8086, etc.) 32-bit computers (IBM 360, VAX, 80386, ARM, etc.) 64-bit computers (everyone!) It remains to be seen if I'll make it to 128 or 256... Son of a bits! --- https://apple.slashdot.org/story/17/06/07/0538233/apple-to-phase-out-32-bit-... Apple To Phase Out 32-Bit Mac Apps Starting In January 2018 Apple will be phasing out 32-bit apps with iOS 11, and soon the company will make the same changes on its macOS operating system. During its Platform State of the Union keynote at the Worldwide Developers Conference, Apple told developers that macOS High Sierra will be the "last macOS release to support 32-bit apps without compromises."
