If that is a miracle so is every engineering and scientific effort because most things are hard multifaceted problems. Maybe these aren’t actually miracles but the inevitable products of structured teams of trained people.
That's why I question whether it's actually a "miracle". I don't mean to suggest that it's not quite the feat to make something like that exist, but I see it as more of a representation of where we're at technologically, rather than some sort of improbable, inexplicable thing that otherwise shouldn't be. The fact that the response to my post seems to clearly understand how it exists kinda-sorta supports that, IMO - you can draw a clear path towards understanding how it came to be.
