This is what you wrote (quoting for the nth time):

See where it says "arm". YOU wrote that.

Which (again) you're changing the context.

Where you're referring to Apple Silicon.

In the quoted instance you were referring to arm. Again quoted above.

Sure. And so is the statement that you can run both on the same 64b
processor - as long as they are in different processes.
