doesnt mean the inside one isnt there to protect the outside one.

So whilst you could argue it cold be seen as a failsafe, I would say its primary purpose remains "double glazing" insulation.

For the non-aviation folks, OAT means "Outside Air Temperature".

Everything gets much easier without windows, but many people feel a sense of security with windows. I also prefer a flight without get a feeling of a flying can.

Is that just a TV with a fancy bezel that plays a 24-hour video? $10K seems a lot to drop on something so mundane.

How much easier would it be to design build & maintain aircraft if we did away with (passenger) windows?

It also helps passengers on long flights experience the passage of time as something other than number go up

If you just want an answer to the question > Bleed holes, Captain Joe explains, “allow for pressure equalization between the space between the panes of the window and the cabin interior. Without these holes, the pressure difference between the cabin and the space between the panes would lead to stress on the window.”

And then to answer the follow-up, the double panes are not for safety in case one breaks. They’re for thermal insulation.

This doesn't refer to the double-paned outer window, the pressure window. It refers to the innermost protective pane, the "scratch pane" that keeps greasy fingers and portruding camera lenses from reaching the two "real" windows. It's the hole in the scratch pane people are asking about

My time in the military has made me hate acronyms with a fury.

that's not what's being discussed. airplanes have a hull window and a passenger cabin window that are universally refered to as a single "double" window- at least amongst the general public.

The inner cabin window is absolutely there to protect the hull window.
