But if you have a 64 bit system that works for you, then use it. May as well!
Exactly, that's my point, if it works use it.
A 64bit Raspbian would be nice, but Debian based OS's are for nice stable everyday usage.
There are other OS's that are more bleeding edge, that use the latest drivers, that may fix old bugs and have unknown new bugs.
People sitting twiddling thumbs saying "I'm waiting for Raspbian64" could have a long wait.
There is a lot that needs to work and perhaps some stuff that may never work?
Linux is a multi user, multi tasking, General Purpose OS.
Lots of times it may be overkill for a single person single task use, like gaming.
Gaming does tend to require more from the hardware than most things
For IoT it could be single task and no user, even 8 bit CPUs can do most of this.
It is only when WiFi/BT comms gets involved that 32bits comes in handy.
So why is 64bits needed?
Insert reason here __________
a) Some people might like to know answers before they have the need.
b) Some people might have a job that requires them to know the answers just in case anyone asks.
c) Some people are just curious or like living on the edge of technology.
d) Some people know it could be done but need to learn the skills to do it.
e) All of the above
What percentage of Pi users actually need a 64bit OS? I suspect it is very tiny.
But Pi's rely on a Linux OS infrastructure, that infrastructure is nearly all 64bit now.
The thousands of people involved in all the code that keeps things like GCC, Clang, LLVM, Debian, Arch, Fedora, Ubuntu, Windows, Chromium, Firefox, Mathematica, Gimp, Blender etc etc all ticking along use mostly 64bit tools.
Out of all these people and companies like Intel, Microsoft, Google, Mozilla, IBM, ......,
RPF is a tiny, tiny piece of it, but pulling way above their weight
There will be an official RPF 64bit OS one day.
We just have to buy more Pi's so they have more money to hire more people to do it.
Or we could just wait or use what works now.
This question will pop up again and again "Why is there no 64bit Raspbian OS?"
Does the OS have to be made by RPF? Does it even have to be Linux?
Pi's are pieces of hardware that run software.
That software can be anything, perhaps one day, even Windows?
When you buy a Pi it may come with a SDcard with software on it
Noobs allows the user to pick an OS, but there is no contract that says you must use one of these OS's.
People are free to use what works for them, that freedom is more important than just one OS.
Unless of course you want to teach coding to kids(or oldsters) then you would be silly to use anything but Raspbian.
Apple has a big presence in schools here in Oz, iPads, Macbooks, but can you learn coding on them?
They really very expensive for performance not much better, starting from - 1.2GHz dual-core Intel Core m3 with Turbo Boost up to 3.0GHz and 4MB L3 cache. Mind you their displays are really nice.
Why is there no Pi display with retina resolution is a more important question than 64bit OS's.
Wait for the Pi4? Not really, the PiTop V2 is probably close enough at 14" 1980 x 1080?
Is it the display that makes Apples so expensive? A Pi $35 display?
Another brain dump sorry, it's 41C here and no aircon, too hot to program
