No. What is the full context of this quotation? I'm pretty sure Srila Prabhupada was indicating that the World Trade Towers were the tallest buildings in the world but with the modern day thinking of "bigger is better"- there will be taller skyscrapers and the two towers will seem like nothing in comparison.

Prabhupāda: Bad condition, good condition, that is another thing. But you get it. You get it. Bad condition, good condition, that is my consideration, but things are available. Even the best apartment in India, that is not a good apartment for America. This is simply my mental concoction: "This is good; that is bad." I am thinking, "It is the best;" another may think, "Oh, it is lowest." The hog is thinking stool is very nice food, and I am thinking, "What is this nonsense thing?" So "best" and "good", it is simply mental concoction, it has no value. Just like these western people, what is their ultimate standard of best, nobody knows. Nobody knows. Just like hundred years before, there was no skyscraper building, but now even best skyscraper building is not best. So where is the standard of best and... It is all mental concoction.

Sudāmā: Just like in New York, at one time the Empire State Building was the biggest; now they have built two buildings that are the biggest in the world now.

Prabhupāda: Yes. Now someday it will be lowest.

Satsvarūpa: Yes, already in Chicago they're building one, a Sears building.

Bali Mardana: Bigger.

Prabhupāda: So what is the standard of best and lowest. There is no standard. This is called māyā.

Bali Mardana: Many philosophers have tried to define what is the best.

Prabhupāda: Eh?

Bali Mardana: Many philosophers have tried to define what is the best.

Prabhupāda: They cannot.

Bali Mardana: It's not possible.

Prabhupāda: They cannot. It is not possible.

Bali Mardana: They have no Absolute.

Prabhupāda: No. They have no idea. Mental speculators, they are no good. (wind noise) Mental speculator means harāv abhaktasya kuto mahad-guṇā manorathena [SB 5.18.12], manorathena by the mental plane, airship, he's simply hovering. They have no standard.

Bali Mardana: So a devotee does not have to cogitate too much. Whatever satisfies Kṛṣṇa, that is best.

Prabhupāda: That's all. Kṛṣṇa is best. That's all. And whatever is done for Kṛṣṇa, that is best. That's all. We have got a standard; therefore we are satisfied. "Even in distressed condition, because Kṛṣṇa has given me distress, so-called distress, it is not distress. So this is all right." Because here, distress or happiness, they are simply mental concoction. Dvaite bhadra... I am in the material existence—that is my distress. That distress has to be removed, not this temporary distress or happiness. (japa)
