I love clips like this that completely remove all context. The building was on fire for hours. If you watch the entire collapse, you see parts of the building collapse at different times. The fires were so intense, flames were shooting out of the windows like a blowtorch. Gigantic chunks of the other two towers pierced the building like swords.

I've seen the video of the fires but I haven't seen an angle that shows parts of it collapsing at different times. Would you mind sharing?

That's it? Alright. That's not what I visualized when you said "parts of the building collapse at different times." I thought you were talking about exterior parts. Though it's technically fair to say the inside collapsing before the outside is "different parts."

In regards to the simulation, it's actually great evidence for the opposite side of the argument - NIST was not able to simulate a collapse that appeared at all similar to the actual collapse.
