"Over the past 75 years, the performance, efficiency and information
density of computers have each increased by a factor of about one
trillion..."
My comment:
One thousand: 10**3
One million: 10**6
One billion: 10**9
One trillion: 10**12.
A factor of one thousand is always a game changer. We are talking about a factor of one thousand, thousand, thousand, thousand.
