I am not OP, but looks like (s)he's trying to say that Rome was not the paragon of science and invention, and indeed the major action was happening in Asia. Rome was a great civilization, but it paled compared to the
combined power of Asian civilizations, which was the scene of multiculturalism, trade, philosophy, science, and prosperity.
Now to nitpick your claims:
> Indians devised the decimal system, wasn't adopted by the rest of Asia
I'm pretty sure the Persians, Arabs, Tibetans, Samarqand, and South-East asians were using decimal system extensively. It was adopted pretty much widely in Asia. BTW India is in Asia, and that makes them Asian.
The compass was adopted by the central asian and south asian sea fairing states. It simply didn't leap from China to Europe.
> they had by far the most advanced architectural techniques at the time.
Which is a grand and unsubstantiated claim. The Great Wall Of China, Indus valley grand megapolis, Persepolis etc stand witness to the grand architecture of the East. Rome while had great architecture, wasn't necessarily superior to any of these.
