An estimate of the number of people who ever lived on Earth made by the BBC in 2012 was 107 billion.

Let's round that up to 110 billion people.

Say all those people in the entire history of the Earth each lived to the ripe old age of 100.

So they lived a total of
110e9 people * 100 years * 365 days = 4.02e15 person-days

Let's say they each ate 3 meals a day every day using brand new pairs of chopsticks per meal.

4.02e15 person-days * 3 meals-day * 2 chopsticks = 24.1e15 chopsticks.

That's 24.1 times ten to the power of 15 or 24.1 quadrillion chopsticks.

Yet even by 2014 we were making hundreds of quintillions of transistors
per year. That's 100 times ten to the power of 18, nearly four orders of
magnitude higher.

And of course we don't all live to 100 and we didn't all have three
meals a day in all of history using a brand new pair of chopsticks each time.
