I think it helps a lot grasping TW
IS a Quine.
Quines are usually thought experiments in computer science. A Quine is a program (or system) that is capable of SELF-CONTAINED SELF-MODIFICATION. Its output is its input. That means it CHANGES ITSELF. Next iteration its persistently different than prior.
BUT TW is NOT a thought experiment. TW is a very rare example of an actually working Quine for practical ends.
That is both unusual and important.
I keep trying to convince tech computeristas this is very significant to no avail. They say, so what?
IMO the architecture of TW is FUNDAMENTALLY Quine, and grasping that helps A LOT.
Best wishes
