Quick, without doing any kind of Googling or calculation: if I asked you to count 3B grains of rice by hand, how long would that take you? How big would that pile of rice be? How long would it take you to eat it?

A billion is already unfathomably large. If you think it isn't, you just haven't tried imagining what a billion of anything would be like.

Yes, big number better, everyone gets it.

The point is that you’re deluding yourself if you think that there is any difference in terms of relative “unfathomability” between 3 billion and 300 billion.

3 billion generates more in interest per day than 99.99% of people make in a year. That’s unfathomable volumes of wealth for even the very rich.
