That really depends on what their long-term goal is. If the speculation & rumors about an eventual ARM transition have any merit at all, then sunsetting 32-bit support now can help them smooth that transition, since they'll have a lot less work to do to implement whatever Rosetta-esque dynamic binary translator they would need.
- WorldMaker 7y agoMicrosoft and Qualcomm together supposedly just invested tons of money in making sure that x86 emulates well on ARM64, but apparently had little success emulating x64 on ARM64. If the speculation and rumors about an ARM transition have merit, it seems backwards to sunset x86 and not x64. Which it seems unlikely that Apple could do in secrecy what Microsoft + Qualcomm could not do (very publicly), but I guess all things are possible.
