Raspberry Pi 4 maximum RAM is 4Gb and so its memory is completely addressable by a 32bit OS
all the code available for Raspberry is a 32bit code
are there any meaningful and reasonable advantages to run a 64bit OS?
This a background question behind all the recurring searches for a 64Bit OS per Raspberry Pi 4 and even for Raspberry Pi 3.
If there aren't any reasonable advantages to run a 64bit OS on a Raspberry Pi 4 due to its limits in RAM size why compile, offer and search for a 64bit OS? Would it be even worse than run a 32bit OS?
